- Bring one less tank or healer, seriously that's the best thing you could do here. If you really want to stick with your current roster for whatever reason just pop bloodlust 10-15 seconds before entering the intermission and recheck your potion/cooldown usage there to make sure it's not a question of a mere second
- Can anyone else handle the engineer? Destruction warlocks are argueable the strongest aoe class in the game (due to how their mastery work), having both on the adds should reduce the risk of dying to them tremendously. We never bothered with the iron star for killing them of, it's just to risky to have those adds around for half a minute.
- Stop dieing to Annihilate. It's not hard, stay on the boss and stop wasting progress time on such a trivial mechanic. I just skimmed through some longer tries and it's hilarious. If anybody misses the buff have them use personals they might've used on the whirl, better getting there than dieing beforehand.
http://worldoflogs.com/reports/rt-yn...pes&boss=71865 if all of your team manage to get the buff it should get tremendously easier to heal through it, allowing your tanks to eat more stacks for additional vengeance and basically makes it safer.
Don't forget that this fight like all major endboss fights is a dance, you need to learn all steps and repeat those over and over. A lucky 24 energy try won't help you with that and you need consitence in your tactic, you don't want to waste half of your progress wiping *before* your next actual progress step, ie in the intermission because the wrong people didn't get a buff or couldn't achieve a lucky crit chain.
Haven't seen a log of solo tank + solo healing it with a warrior, but solo tank + duo heal works just fine.
