Our guild is finally up to chimaeron and started tries on him yesterday. To cut a long story short, we only got to the final phase once. We were 9/10 guild group, one of the healers was a pug. It was an interesting fight but quite stressful for healers, so I thought I'd see how the rest of you deal with it.
Our tactic was to have me heal my group, the pugged disc priest healed his group and our holy tank healed himself and the offtank.
How I decided to deal with it was to only use one flash heal on every person below 10k. It's fast enough to let me save two people in my group if needed, and it heals ca 15-20k. On massacre, I use one PoH and one CoH and everyone is safe. When no one is my group is in need of a heal, I tried to keep renew and PoM on the offtank to help the holy pala. Once feud starts I immediately throw Sanctuary on the ground and PoM on myself, I've already made sure a fresh lightwell is up. I then spam PoH with CoH on cooldown.
Anyone have any extra pointers if it can be made even safer or effective? (Our main issue was the pugger not being able to keep his group up even if I told him to use the same tactic I did).
Another thing, I later uploaded the tries on WoL and saw that I peaked at 40k HPS during feud. Did my logs bug out or something? 40k sounds completely ridiculous. Would be cool if other people here shared their raids HPS so I can see if our guild is doing acceptable in that area.
