Updated for Dragonflight Prepatch: 11/20/22
Welcome to “Improving your DPS: Revisited”. Some of you may remember the “Improving your DPS” guide that Quetzie wrote during Uldir to help us improve as we moved into harder fights (remember dipping our toe into Mythic for the first time? Ah, nostalgia!). Consider this the successor guide as we move into a brand-new expansion and hope to hit the ground running as a more well organized group. This guide is co-written by Quetzie (Mythic Raid Lead and Person-Who-Thinks-Alts-Are-For-Suckers) and Tiraffe (Mythic Raid Lead and person-that-did-every-Balance-of-Power).
In the first guide, Quetzie spent most of the time focusing on those who might be new to raiding or who were aware of their faulty DPS. In this guide, we revisit some of the tips that can help new players, but we also want to drill home that every level of player can find a place to improve. Even on the mythic team, nobody is perfect. There are always rotation gaps, mechanical failures, and basic preparation that can be improved upon.
Here are the topics this post will discuss:
- Streamline & Optimize
- Rotation & Opener
- Pre-Combat Preparation
- Class Resources
- Dragonflight Optimization
- Asking and Receiving Help
Streamline and Optimize
Before we get into anything complicated, like external sites or addons, ask yourself: are you making the game harder than it needs to be?
Disclaimer: Most of this post will discuss using the default keybinds. If you have changed a lot of keybinds you may need to find the ones we refer to here.
Ability Clicking
If you click your abilities on your action bar with your mouse button, you’re already setting yourself up to be at a disadvantage.
- Keeping your mouse (and eyes) glued to the bottom of your screen will make it harder to dodge mechanics or see when you need to take specific actions.
- Clicking is inherently slower than using keybinds, as you have to move your mouse around the page
- With Dragonflight, every spec will have too many rotational buttons to make clicking your rotation viable
- Your main rotation should never be click-activated.
Clicking some abilities isn’t necessarily an awful thing. A lot of classes have abilities that get activated on 3 or 5 minute cooldowns. Tossing those at the end of an action bar and clicking on those isn’t going to affect your DPS in a significant way.
Action Bar Arrangement
Consider which spells are the most important spells in your rotation. Which ones do you cast the most? Put those spells farthest to the left on your action bar, OR wherever is most convenient for your hand. If you’re not sure which spells you should be casting the most, scroll to the Opener & Rotation section to see what you should be prioritizing.
For example, I (Quetzie) put my most “spam” abilities, in this case Wrath and Starfire for balance druids, on the ‘3’ and ‘4’ keys on a QWERTY keyboard, since that’s closest to my pointer finger. The Moonfire and Sunfire DoTs that balance druids have would be placed on the ‘1’ and ‘2’ keys, since while they are spammable for aoe, they only need to be hit occasionally in single target using the ring/middle finger.
Also, consider grouping spells with similar purposes nearby one another. A troll balance druid has two 3-minute cooldown damage buffs: Berserking and Celestial Alignment. Keeping them right next to each other on the action bar makes it easy to remember to use them both at once for extra damage. (If you have an on-use trinket, I’d put it next to them as well.) If you happen to play multiple specs or classes, consider having similar spells (like your interrupts) attached to the same keybinds as well, as that will also make it easier to switch around.
Remember that you have other action bars available, but they’re not enabled by default. You must enable your extra actions bars in the “Options -> Gameplay – Action Bars” menu. In Edit Mode, consider using “shift+1” or “ctrl+1” bindings and onward for these other bars, as some specs have a high amount of spells in their rotation and the 1-6 keybinds may not cover them entirely. Remember that you can create macros to save even more space on cluttered action bars. For more information on macros, check out Cool Tricks to Show Your Friends.
Keybind Practice
After you’ve rearranged your action bars, find yourself a target dummy and just sit there. Take your hand off your mouse! Lean back and just get used to pressing your keyboard buttons for damage. Start small. Start by getting used to casting 2 spells using your hand, and then work your way up from there. Repetition is key to developing muscle memory, and you’re going to be relying a lot on that muscle memory during hectic boss fights! Speaking of which, it’s easier to have a default hand position on the keyboard to return to, as this will help make sure you don’t lose track of where your hand is and end up pressing the wrong button.
When you practice, avoid looking at your action bar. You want to commit this to muscle memory. If you have to, cover the bottom portion of your screen with a piece of paper or something. The point is to keep your eyes up. It’s a bit like driving – you need to watch the road, not your speedometer. Eventually you’ll become comfortable enough with driving that you only needed to glance down once in a while to reassure your speed. The same thing goes for your rotation, you only need to glance down to react to procs and the occasional cooldown. Keep your eyes in the middle and you’ll see incoming mechanics and boss spell casts!
Gaming Peripherals
If you still struggle with making macros and an excess of keybindings, purchasing a gaming mouse, keyboard, or keypad may help you. Gaming mice usually come with 9 or 12 “thumb buttons” that you can use to easily access spells. You can use software to re-bind these buttons to other keys besides 1-12. Gaming keyboards or keypads usually come with additional buttons above or to the side of your keyboard, specifically made for additional macros and complex bindings. All of these buttons can be completely re-mapped to best suit your available keybindings.
Improving your UI
This is related to your keybinds, but deserves its own section. Dragonflight saw a major overhaul of the base UI for the first time in its history. We won’t go into all the details here, because there’s already a post on the site that covers it: Customizing the new UI: Tips, Tweaks, and Addons
You can help yourself get used to not looking at your action bar by adjusting your UI with specific addons and weakauras. There is a delicate balance to this. On the one hand, you want your UI to show you important cooldowns and actions happening on the fight. The closer to the center of the screen you have your UI elements, the shorter the distance your eyes have to travel. On the other hand, make sure your UI isn’t too cluttered, and that all the information you can see on-screen is actually important – make sure you can actually see what’s going on.
Moving away from clicking your abilities is going to be weird and it’s going to take time. Using keybinds instead of clicking will increase your actions per minute, and saves your mouse for moving your camera and/or character, allowing you a faster reaction time for mechanics. You won’t like it at first. In the short term, your DPS will drop, because it’s new and you’re fighting old habits. But it will grant you with significant improvements in the long term, we promise!
Related to UI is the use of addons and weakauras. Our Discord has a repository of useful weakauras and addons that are kept up-to-date for each patch / raid, in addition to submissions from members of their favorite / useful finds. This goes beyond “big WA packs” and into nuances like auto-selecting options at NPCs, alerting you of item buff s/ debuffs, or even fun ones like the Soulshape journal.
Keyboard Turning
Keyboard turning is the term for when you turn your character using the A and D keys. If you have to turn your character model or run away from something, pressing forward and left or right is a painfully slow way to go about doing it. More often than not, you’ll fail the mechanic and potentially wipe the raid or dungeon in the process.
The proper way to dodge mechanics is one of:
- Strafing (Q and E)
- Strafing with your mouse (right-click and press A or D)
- Turning your camera and running (right-click your mouse and drag, then press W to run forward)
- Hold down both the left-click and right-click on your mouse to run forward, allowing you to do your rotation using keybinds on one hand and steering on the other.
Practicing turning and dodging in combat
Target dummies can be found in most major cities. I find the target dummies in Dazar’alor very useful for practicing turning around quickly, whether to target newly spawned enemies or to get used to mechanics that require you to turn quickly, but the good news is that Valdrakken also has target dummies. Go to Valdrakken and go to the target dummies (as seen in this map of Valdrakken). Position yourself in the middle of the room, facing the Raider’s Training Dummy. Start casting spells. Then, right-click your screen and drag it to do a full 180* turn, so you’re facing the regular Training Dummy. Target the basic dummy, and continue casting. Repeat this often and you’ll see how much faster it is than pressing A or D to face a new target!
For a real-life application, think about the Jailer’s Chains of Oppression mechanic. You have approximately 2 seconds after getting pulled on top of him to get out of his death circle. Keyboard Turning is not going to turn you fast enough. Right-click-dragging will save you time and immunities!
Strafing is another easy way to dodge mechanics. Think about the heroic N’zoth fight. We group up tightly and then move sideways via strafing on the count of “ONE” to drop the corrupted puddles on the ground. If you’re relying on keyboard turning, you’re taking too long to dodge mechanics and may take excessive damage.
In front of the dummy, get used to strafing during your rotation. Cast 5 or 8 spells, then press and hold Q or E. Cast a few more, then hold Q or E to get back to your normal position. Rinse and repeat.
If you’re REALLY struggling with the strafing habits, unbind A and D from left and right altogether (Key Bindings – Movement Keys). Rebind them as your left-strafe and right-strafe. Some people prefer this setup!
Enemy Targeting
Generally speaking, clicking an enemy’s healthbar or model to try to cast spells is going to be a problem. Often they will be surrounded with allies, and unless you have a specific setup so that you can click through allied healthbars and bodies, you’re going to click on them from time to time. By default, press Tab to cycle through enemies in front of you. (There are other addons and setups that may be more accurate, but if you click enemies as a rule, this is a good base.) Especially in a fight where you have to cycle between a small number of targets, tab-targetting will help you immensely. It does lose its value when you have tons of add spawns (think Hivemind with the little bugs). Feel free to repeat the previous exercises in the Keyboard turning section using tab-targeting.
For fights with larger number of targets, or priority targets, tab-targeting is going to lose value. You can easily spot priority targets based on their nameplates. Enable Enemy Healthbars by going to “Options -> Interface -> Nameplates”. Click “Always show Nameplates”, and make sure “Enemy Units” is enabled. This will allow you to select an enemy who is either at the most health or the least health, whose buffs are running out (or who needs debuffing), and more, depending on your setup.
Camera Positioning
Right-click-dragging and left-click-dragging will both reposition your camera. However, right-clicking also repositions your character model. Left-click-dragging only moves your camera. While casting spells at the dummy, left-click-drag your screen so you’re facing your character. You haven’t moved, but now you can see the angry face that your character makes when it attacks or casts spells. Left-click-drag will give you a good vantage point for mechanics in some fights or dungeons. Consider the horrible camera angles in Grimrail Depot; left-click-dragging your camera to see, without changing the facing of your character (and thus cancelling casts or attacks) is invaluable. Moving your camera without moving your character will help you successfully execute these mechanics.
Right-clicking is better used for mechanics where the direction your character is facing, not the direction of your camera, affect the mechanic. Jumping into the holes on the Jailer requires your character to face a specific direction, lest they be thrown off the edge. Using right-click positioning is better than trying to shimmy your character into position with WASD.
Game Sounds
We have no idea how, but some people play the game without sounds enabled. You people are a mystery. The game has constant buzzings, warnings, and other effects when things are going on around you. “But those are annoying!” Well…that’s kind of the purpose, isn’t it? Game sounds tell us when we need to dodge mechanics, when an enemy is powering up, when we’re out of range, when spells are uncastable, and so much more.
For example, it’s far more difficult to catch that an enemy player spam-purging your buffs away by staring at your buffs disappearing than it is to hear the loud sound effect from them casting Purge/Dispel Magic repeatedly. It’s harder to catch the boss saying he’s casting the easy-to-avoid area attack in chat, but hearing the boss shout it through your speakers can’t be missed.
If you’re struggling and have your game sounds disabled, please turn them on. Across the board, people will react to sound cues faster than visual ones. You don’t need music, but sound effects will make your life significantly easier.
Rotation & Opener
Now that you’ve moved your spells and downloaded some add-ons it’s time to make sure you’re actually casting your spells in the right order. Hopefully, you’ve been doing that all along. If you’re grey parsing regularly, chances are you’re not. So, let’s try to fix it!
First, check the resources at the bottom of the page for your class discord, websites, etc. They’ll often list openers and rotation priorities for you.
Openers
Usually, raids will start a timer of some sort in order to make sure everyone starts hitting the boss around the same time. Members of the raid have the option to precast on a boss, by starting a cast and then having that cast finish after the timer hits 0. Different classes will have different ways to begin the pull, but so long as you don’t pull early and get someone killed, you’ll be fine. It’s possible that someone has already taken note of the “perfect” opener and rotation of spells and wrote down exactly what you should do.
Let’s take a look back in time at the Destruction Warlock opener one would have used historically for Taloc, which is a single-target fight (openers may change for multi-target fights), during patch 8.1.
Single Target:
- Pre-pot and cast an Incinerate when there’s 3 seconds left on the pull-timer
- If you’re talented into Cataclysm use this to apply Immolate, if not then manually cast Immolate to land as the boss is pulled
- Cast your Summon Infernal and Dark Soul: Instability aswell as any on-use trinkets you may have
- Cast Chaos Bolt
- Cast Channel Demonfire if talented
- Cast Incinerate
- Cast Conflagrate
- Cast Chaos Bolt
Here is an old timeline sample from a Warcraftlogs fight of a Destruction Warlock on heroic Taloc. Let’s take a look to see if this is lining up with the “perfect opener” above!
(Not sure how to get to the timeline? TLDR: Open a log, click the boss name, click the name of the person you’re looking for, and click “Timeline” in the upper right. You can find more information on navigating Warcraftlogs in the “Warcraftlogs for DPS” post, though it’s a bit old and outdated in its actual analysis.)
Uh oh. Looks like some things aren’t lining up. Immolate was cast very late into the opening rotation, not as his second cast. Chaos Bolt didn’t follow Conflagrate. Incinerate wasn’t cast next, either. And there’s a lot of empty time with no spells cast in just the first 15 seconds. Now some variation is expected of course, but it’s possible that this person needs to take another look at their opener on this sort of fight.
Different classes have different requirements for openers. Some classes have openers that don’t change based on the fight style, where others (especially “ramp” classes) are incredibly dependent on a performing a specific opener to set the pace for the fight.
Standard Rotation
Standard rotation is again going to vary based on class and on the fight. Some classes are “priority spell” based, especially if classes are proc-based or receive procs as part of their rotation. Others are pretty easy “Cast spell 1, spell 2, spell 3 in order”. Again, check resources for your classes!
For example, here’s the BFA Shadow Priest rotation for single-target fights:
- Out of Void Form
- Apply Shadow Word: Pain and Vampiric Touch if not present on the target
- Cast Void Eruption
- Cast Mind Blast
- Keep up Shadow Word: Pain and Vampiric Touch
- Use filler
- In Void Form
- Cast Void Bolt
- Cast Shadowfiend / Mindbender when you feel you need help maintaining voidform
- Cast Mind Blast
- DoT new targets/maintain DoTs
- Use filler
Note that BFA Shadow Priest is very “spell 1, spell 2, spell 1, spell 2, spell 3, repeat”, except for refreshing your DoTs and the occasional cooldown. The rotation for Shadow Priest in Dragonflight is much more involved than its BFA iterations and should not be clicked through at all. The focus is still on maintaining all 3 DoTs (including the returning Devouring Plague) and maximizing Void Bolt/Mind Blast casts, but SL Shadow Priest now has procs from Dark Thought and Dissonant Echoes to manage. Combined with a less-rigid talent tree, your rotation will also change drastically for aoe, dungeons or pvp.
Rotation Nuances
This will just be a rough list of things to keep in mind when doing your rotation:
- Try to avoid capping resources. Most specs have a maximum amount of resource they can hold at one time. Be sure to spend it before any more resources you generate are wasted.
- Make sure to cast your spec’s damage cooldowns when there is not upcoming mandatory downtime. Some specs are really reliant on their damage when their cooldown is active to make up for damage when it isn’t. These tend to be long, 2-4 minute cooldown spells. Players should be using any on-use trinkets during these cooldowns.
- Make sure to use your regular abilities on cooldown if you aren’t pooling resources for a big cooldown.
- For stuff on shorter cooldowns that require resources, make sure to hold onto those resources so you can cast the cooldowns when they come up.
- Certain specs will have “mandatory” downtime due to how the spec functions (Feral Druid, Assassination Rogue, DK Runes) where you have to wait and pool resources before you can cast another spell or ability
- ABC, or “Always Be Casting”.
- Getting targeted with a mechanic is not an excuse to do nothing
- If you have to move, almost every class has an instant-cast ability, even if it’s something like a shield that does no damage
- Do what you can to stay in range of targets and allies – normally, if you’ve gone out of range, you’ve gone too far
In short, wasting resources = bad. Cooldowns themselves are resources. Use all of the tools in your spellbook when appropriate.
Practice, Practice, Practice
Download a damage meter while you practice. We recommend using Details! Don’t watch the meter during combat, but set yourself a timer (3 minutes, 5 minutes) and start your rotation. After the timer stops, look at how you did. Keep practicing until you see those numbers go up. Any spec that has pets needs to set their pets to passive when your timer ends so that combat ends around the same time and you’ll get more accurate numbers.
You can also use the damage meter to compare your performance to a sim. That said, nobody pots on target dummies, so don’t worry about matching your sims exactly. You can read more about simming in our quickguide to simming.
Active Racials
There are several different categories of racials. If you find yourself forgetting to use them, consider putting them near other spells of a similar type on your action bar.
These racial abilities can be used if you have to move or fill in mandatory downtime and want to ABC:
- Goblin Rocket Barrage
- Nightborne Arcane Pulse
- Vulpera Bag of Tricks
These racial abilities remove CC:
- Undead racial Will of the Forsaken removes fear, charms, and sleep effects
These racial abilities provide DPS, HPS, or other “steroid” increases:
- Troll racial Berserking
- Mag’har Ancestral Call
- Orcish Blood Fury
These racial abilities can heal either the character or someone else:
- Zandalari Regeneratin’
- Vulpera Bag of Tricks
- Undead Cannibalize
- Dracthyr Visage (out of combat only)
These racial abilities provide extra mobility:
- Goblin Rocket Jump
- Highmountain Tauren Bull Rush
- Dracthyr Rescue (moves yourself and someone else) and Hover
These racial abilities provide extra CC:
- Tauren War Stomp
- Pandaren Quaking Palm
- Highmountain Tauren Bull Rush
- Nightborne Arcane Pulse slows enemies
- Blood Elf Arcane Torrent is an aoe offensive dispel.
- Dracthyr Wing Buffet and Tail Swipe
Pre-Combat Preparation
Also covered in the Introduction to Raiding guide. Things to know before you start a fight include:
- Knowing your spec’s rotation based on the style of the fight and your available gear/talents/traits
- In Dragonflight, you can save up to 10 talent loadouts per class to make ti easier to swap between fight styles
- Common fight styles to have talent builds ready for: single target, 2-target cleave, 3+ target cleave, spread AoE / council fights
- Knowing your spec’s preferred stat distribution
- Some specs have multiple builds, often with very different stat distributions
- Simming your gear/talents/etc. for damage output
- Selecting the right talents, based on the fight
- Selecting a good tmog, Druids and Evokers too
- Making sure you have the right sockets/enchants on your gear, based on the stats needed.
- For the following specs/classes, make sure your higher item level weapon is in the main-hand slot: Rogues, Fury Warrior, Enh Shaman, Frost DK, BM/WW Monk, and Demon Hunter.
- This will cause you to do more damage. The only time this changes is if you have a weapon that can proc an effect from on-hit, which means it goes in the main-hand slot, provided that it does more damage despite the loss in item level. This is where you’ll need to sim which piece to put in which slot.
In addition, it’s a good start to have the following:
- Personal health potions
- Phials & Battle Potions
- Personal stat food (If you have access, you can pull these from the guild bank)
- Reference your specs/build’s stat distribution for if you need stat food or if you need to wait for the raid to put down a feast for mainstat
- Ensure all your chosen talents are on your bars.
- Make sure any on-use trinkets are on your bars
- Feel free to combo these trinkets with any damage/healing cds
- The same goes for any active talents, make sure they’re on your bars
- Make sure to actually use these too
- You know what, put everything on your bars
- Remember to enable all the extra bars like we taught you earlier
- You know what, put everything on your bars
- Make sure to actually use these too
- Hunter make sure to have one pet of each specialization
- Rogue should apply poisons are applied to weapons
- Enhancement Shamans should apply their weapon imbues
- Warlocks and Hunters should summon pets before a fight
Class Resources
There a lot of resources for each class and specialization available. These resources cover talents, rotation and more.
Discords
You can look into the various class discords for the most up-to-date information. These discords should have a frequently-asked-questions section available as one of their text channels, though some of them may be incomplete.
Class Websites
Some of these discords also have specific websites that can be visited. Please note that these are often not as up-to-date as the class Discords and are best used as a general reference:
- Priests: https://warcraftpriests.com/
- Holy Paladins: https://wingsisup.com/
- Druids: https://www.dreamgrove.gg/
- Rogues: http://www.ravenholdt.net/
- Monks: https://www.peakofserenity.com/
- EleSham: https://stormearthandlava.com/
- Mages: https://www.altered-time.com/forum/
Note: for some of the ones that aren’t listed, make sure that the information you’re looking at is actually up to date.
Generic Websites
You can also check out the class guides available on Wowhead or Icyveins. Many of these guides are spec-dependant – they may be just as good as the discords, or may be a few patches out of date, but still usable.
We personally do not recommend following the guides from Noxxic or Wowmeta due to them being either very out-of-date or incorrect. There are several other sites that are inaccurate as well. If you find one not mentioned on the list, be cautious and vet the information before using it.
Streamers / Youtubers
A lot of people really enjoy watching experts of their class on Youtube or Twitch. While we’re not going to list every popular talented streamer, here is a short list. Additionally, you can find several recommendations from this reddit thread from October 2022.
- Frost / Unholy DK: BicepsPump
- Enhancement Shaman: Waves
- Healing: Yumy
- Feral Druid: Psybear
- Tanks: Dorki, Darkmec, Naowh
- Warrior: Critcake
- Frost Mage: OkayMage
- Shadow Priest: Publik
- Rogue: Infexious
- Balance Druid: Naguura, Tettles
- Demon Hunter: Jedith
The Mandatory Section About Class / Spec Talent Choice
It doesn’t really matter what class or spec you play you use for normal and heroic, so long as you are still playing to the best of your ability. We likely won’t ask anyone to switch classes for heroic progression. Likewise, the raid leads similarly don’t take responsibility for people’s class/spec choices, so long as you try your best with what you picked. If you do well at a “subpar” spec you have fun with, you will be doing better than if you do poorly with an “optimized” spec you don’t enjoy.
If you’re not sure what the best talents choices are for your spec, we recommend checking Subcreation. Subcreation is a site that aggregates data from the top Mythic and Heroic Warcraftlogs parses and displays it in an easy-to-ready format. Subcreation also includes a “copy talent build” function, and a link to a raidbots sim for each talent build. SC shows how many people are using specific builds, and how many are using specific talent choices. It highlights your Capstone and Choice nodes, but includes information for all abilities as well.
Asking for and Receiving Help
So you’ve read the guides and realize that you need help. That’s awesome!
Asking for Help
Tiraffe and Quetzie are generally always happy to help those who ask. Each one has different strengths and weaknesses, as well as availability. Feel free to ping them in the DPS channel to set something up, even if you would rather the conversation move to private Discord PMs after. Providing specific feedback or using examples is a great way to springboard the conversation – “I’ve tried using this talent, but I am struggling to remember when to use it most effectively”, or “I have all the right talents, but I feel like I’m using them in the wrong order – my burst damage is way too low.”
However much time you want to spend on improving is up to you, but if you want us to invest a lot of time, be prepared to invest a lot of time in turn. If we send you a thorough discord essay with graphs and cast timelines, you don’t necessarily have to respond in kind – but do try to show that you’ve made an effort to work on some of the points we suggested. You will need to spend the time reading what we wrote – don’t expect a tldr – but we’re happy to have a dialogue to break it down into an easily understood plan of action for you. Remember that we may spend several hours poring over DPS logs, making charts, comparing and contrasting between you and others, researching specs we don’t play, and more, all in the interest of helping you out. Please respect the amount of time we spend researching & developing these personalized write-ups.
You may also want to set up a time to talk in Discord. We will likely ask you to stream so that we can see how your keybinds are set up, what your UI looks like, and if there’s any glaring issues that can’t be tracked via damage meters (like clicking abilities or keyboard turning).
Unsolicited Advice
While we trust our raiders to be mostly self-sufficient, we often take note if someone is under-performing in certain metrics. If it continues over multiple weeks, the Raid Leads may reach out to talk with you or ask an expert in your class to talk to you. This isn’t an insult – it means that we’ve spotted a potential problem and believe it is within your capability to resolve it.
We realize that unsolicited advice from non raid leads may be upsetting, but most advice is coming from a place of good intentions. You can always take unsolicited advice and discuss it with Quetzie or Tiraffe to see if it is a good strategy, or if the other person was unwarranted.
TLDR
Streamline and optimize; practice, practice, practice; prepare yourself. And stay motivated:
