Ah, OK, so I see a couple things we were not taking into account. Like I said last night, those Corrupter tentacles were the big problem, what I did NOT know was that they targeted nearby players. That means that we want everyone to stay at max range as much as possible (which is a challenge because we are a VERY melee heavy raid). I know dispelling the Corruption was also a big challenge. I know my shaman’s cleanse is single target and has a 10 second cooldown so I am not a very effective dispeller. I think we need to be a little more specific as to healer duties for some of these fights.
I know what killed me every single time last night was the Corruption, either the stuff spewed by the tentacles or left on my by ichor or accidentally running into a pool of it on the ground.
