When we finish p3 theres about 4 or so up, then during the transition another 15 spawn. We cannot find a strategy that works to kill these things quick enough. We have tried to stack in the middle behind the boss and just aoe like mad but the amount of damage they put out is almost unhealable or it drains our mana almost instantly - making us oom by about 60%.
Is there another strategy guilds have used for this kill? We are doing about 4 waves then 3 waves for p2 and letting the wave after those just go through as we dps the boss to help with enrage timer because we hit enrage 3healing it at 41% and thats without dpsing between phases, only during p1.
If it helps our raid comp is:
demo/aff lock (bm/surv hunter or arms war replacement this week)
Resto sham (ele offspec)
any 10m guilds who have killed elegon 2healing - what did you do for cosmic sparks??
