Started on this fight last night after downing H-Immerseus after 3 tries. Big jump in difficulty. The fight itself isn't logistically hard but we were having serious trouble healing during certain parts, particularly Sun's Desperate Measures.
My question is, how many healers do most 25-man groups run? We were doing 5, but a few of our healers are undergeared (540-ish ilvl). We had a DPS switch to heals for our last attempt of the night and got much further. I'm just wondering if we're going to hit enrage with 6.
