TL;DR - Big tank damage, very nonlethal raid aoe damage, Burns need dedicated healers. Follow assigns and do not deviate.
This fight is entirely on assignments and healers recognizing that Meteor Slash damage is very low priority to be healed. Outside of mishandled Burns, the only way you can wipe is if your healers go off-assignment and a tank dies.
The tank damage is very high and increases dramatically when Stomp is on the target. There’s a few tank-specific tricks to reduce or lessen active tanking with Stomp, but in general, you should track Stomp and be ready to pump extra big heals onto tanks when it’s active.
Other than the tank damage and Meteor Slash, there’s only Burn to account for. Burn lasts for a full minute and ticks every second, but only the last 15 seconds do a lot - the last 5 ticks will hit for 3200 each.
Basically, the play is to have all but 1-3 healers assigned to tanks at all times. No deviating, tanks only. The tank healers need to keep a close eye on who the active tank is as it will swap back and forth regularly. Have pre-casts ready for tank swaps and make sure tanks communicate swaps as cleanly as possible.
Druid is specifically very powerful here as it can maintain full tank healing while also handling the majority of Burn damage. No matter your comp, you will want your Druid to be maintaining LBs on both the active tank and any Burn targets. For the last 15 seconds of any burn, 1 other healer needs to help the Druid out as Rejuv + LB will only be about 60% of the healing required for the DoT. If your healing comp doesn’t have a Druid, you need to have two healers focus on Burn healing for the last 15 seconds.
There’s two common strategies to handle this healing assignment requirement:
The Shaman-centric way: It’s possible to have everyone in a meteor slash group close enough to the tank that CH will reliably bounce from the tank to everyone slashed, meaning that all of them will passively be healed up while the tank is still receiving large amounts of healing. The main downside to this strategy is that positioning is fairly strict as CH only has a 10yd jump range - additionally, topping people off after a final slash can be tricky as the other tank will have the boss and need to be spam healed instead.
The Priest-centric strategy: Have 1 Priest handle all meteor slash and Burn damage (while your Druid assists on Burns with spare GCDs), while all other healers keep tank healing. A mixture of CoH and Renew should be used to top off the raid between Meteor Slashes; however, you will lose some tank healing as in the CH strat the Priest would be tankhealing as well. In this strategy, the Shamans do NOT CH at all as the raw throughput of HW can be necessary for multiple unavoided hits on the tank in a row.
Ultimately, any form of strategy where you have only 1-2 healers assigned to topping off Meteor Slashes and Burns, while the rest of the healers spam tanks, is viable. The keys are just to make sure that the tank healers do not deviate from their assignment for any reason, and have a plan for Burns to be handled.
Druid - This fight has constant, predictable tank swaps. Raids usually do 2-3 meteor slashes before swapping tanks. When one tank hits 1-2 meteor slashes respectively, start stacking lifebloom on the other tank so the other healers have as much time as possible to switch. Extra GCDs should be used on Burn targets.
Paladin - Downrank Holy Lights during normal tank damage and use max rank for stomp healing. If you find yourself getting low on mana it’s better to reduce your healing during the non-stomp periods so that you have the mana to max rank for stomp.
Priest - Burn ticks every second, giving you very high value on PoM versus putting it on tank/raid.
Shaman - This is the best example of a fight where the Healing Wave talents are invaluable, as even if you are using CH to top off slashes, you should be weaving in HW constantly as it’s more efficient and much more powerful at tank healing. If you aren’t using CH to manage the slashes, you should stick to almost purely HW; the Meteor Slash damage is not urgent whatsoever to be healed up right away, similarly to Morogrim’s Quake damage from T5.
