Battle of Dazar'alor
Champion of the LightSingle Target
If you get a second set of cooldowns then line it up with execute phase, unless you think you will get a 3rd set but that is rare since this boss dies quickly for most guilds.
Grong, the Jungle LordSingle Target
If you see the adds are coming up soon then you can save your dragon roar since you will likely get to hit 2 targets with it.
Make sure to save your last set of cooldowns for execute.
Jadefire MastersMulti Target
Many guilds use their bloodlust at different times on this fight and so it is harder to give general advice. Try to have your cooldowns ready for when you bloodlust, and have your last set of cooldowns for execute phase as always unless you can stack it with the buff from Multi-Sided Strike or there are additional adds to cleave.
This is the only boss where I would recommend going Bladestorm over Dragon Roar. The small adds spawn 1 min apart, lining up perfectly with Bladestorm. Make sure you have your last set of cooldowns for execute, and be careful with using Bladestorm towards the very end of Phase 1 so that you have Bladestorm ready for the first set of adds - keep it if you think Phase 1 is done within 25 seconds.
Conclave of the ChosenSingle Target
Just do your normal single target rotation.
King RastakhanSingle Target
As a fury warrior you will probably not go to kill Bwonsamdi and instead stay on Rastakhan.
Make sure to have your cooldowns ready for when you get to cleave the adds that spawn in Phase 3.
High Tinker MekkatorqueSingle Target
Stormwall BlockadeSingle Target
Just blast the bosses doing your normal single target thing. You should switch to adds if they are close to melee or if the timing is so that you are not dropping bad Sea Swells. However, if Sea Swell is coming up it might be better to just leave the adds to the ranged, unless they seem to be struggling to bring the adds down in time and then you should help anyway.
Lady Jaina ProudmooreSingle Target
DPS-wise the important part of the fight is the last phase, make sure to have your cooldowns ready for when the Ice Wall spawns.
If you play Troll make sure to not use Berserking late in phase 2 or you will not get it back.
Use you cooldowns on the Wall of Ice and then again in the execute phase.
Crucible of Storms
The Restless CabalSingle Target
This is most of the time a 2 target cleave fight and for a while a 3 target fight, which means that some different talents are viable although the standard setup might still be the best.
The key to doing high damage on this fight is to have high uptime on the Promises of Power debuff, but that comes with great risk to your survivability and so probably you will not have it up often anyway. Try to get your cooldowns used during the windows of time where you have the damage buff stacked up. Look through logs to see if there are specific times where you seem to reliably get high stacks and get your cooldowns used during those times.
I believe Anger Management would be good for phase 2 since the adds spawn once every minute, meaning you are able to have your cooldowns ready for every new add wave. In theory the same would be true for Bladestorm, however the adds spawn far apart which might make it not worth using since you probably can’t hit all of them with an 8 yards radius. Dragon Roar on the other hand has an increased range of 12 yards which might make it better still - hard to tell.
