I'm surprised to hear you even got him down? Marrowgar on heroic, I've found, is ridiculously overtuned.
We did it with 3 healers, a pally, myself and a droodad. We were doing the "everyone stand w/ the rogues" strategy we used in normal in order to avoid the fires. We found that we had to have everyone scatter 5 seconds before Bonestorm started in order to avoid some of that damage.
We tried to control who he was chasing in the Bonestorm phase on the theory that he always goes for the person farthest away from him in the room. It "sorta" worked, but wasn't quite as controllable as we had hoped.
Our healer core is quite uber. I'm no slouch, and I'm usually 2nd or 3rd on the meters in our 25 mans behind the very same healers that were in this 10 man w/ me. That and we had some incredible dps as well.
In general, Moz...I would agree with you. He's too hard for the first boss in the instance imo. Edited, Apr 26th 2010 9:29am by margeux
Healers are like artists, no one appreciates you until you're dead. (Shamelessly stolen, original author unknown)
