I am the main tank for a casual 10 man raid group. We have been raiding successively for the most part. But the last couple of weeks we have been hitting a brick wall mainly on Ascendant Council. I think its a problem with one of our healers. We can make it to phase 3 with each bosses being consecutively close to 25%. The problem is that the one healer is OOM be the middle of phase 2, thus causing more healing strain on our other 2 and them low on mana by phase 3. Our group is melee heavy which is not all that good for this fight, we run with 2-3 melee depending on which range shows up that night. Our group is mostly: War tank(me), TG war, Frost DK, Lock, Boomkin, Disc priest, resto shaman, and resto druid(questionable healer). With either a DK or druid OT, arms war or hunter being our last dps.
As best a link to the druid healer I can make: chardev org/?profile=137424
