So we are beating our heads against this boss in both 10 and 25 man. Yeah yeah I know, Dreamwalker is srs bzns but we aren't even coming close. We have changed up the priorities for adds repeatedly and nothing seems to be working so here is my latest version of who needs to handle what adds.
Our problems are NOT related to healing. Our problem is we slowly lose a dps here and there and by the 4 minute mark we have on average 6 dps down and we get overrun with adds well before we should be. The best attempt we had ended with her around 80% healed, we had 3 healers coming out of the portals with about a 20 stack and it was over because our dps was all dead.
We lose them to zombies exploding in the raid, dps jumping on worms too early and pulilng aggro and dying, and by the end when we are short on dps a skeleton finishes us off with lay waste.
So here is the latest incarnation of our add management plan. Is there something blatantly wrong with this?
Skeletons
Melee DO NOT CHARGE TO THESE GUYS LET THEM COME TO YOU
Ranged target them ASAP and start burning them down.
Suppressors
Melee - if no skeleton then kick these guys asses.
Ranged - ignore unless there is nothing else up except aboms.
Mages -
Melee - If no skeletons or suppressors then get on her and interrupt every Frostbolt Volley, if you need to setup a rotation then do it but don't let them get that cast off. It's a freakin 3 second cast so there should be no excuses for this cast going off EVER.
Ranged - If no Skeletons then kill these
Zombies -
Melee - ignore them
Hunters - Hunters (1 on each side in 25) will kite these bastards around.
Ranged - If no skeletons or mages are up then kill them
Abominations
Melee - there better not be ONE other mob alive if you are hitting this guy
Ranged - see melee role
NOTE - IF YOU ARE TARGETTING AN ABOM WHEN HIS HP HITS 0 YOU ARE RESPONSIBILE FOR KILLING WORMS. Give the tanks a couple seconds to get aggro on them all. You are also responsible for letting the rest of the dps know you just killed an abom and worms are coming.
When worms spawn they take the #2 priority for ranged (and melee if they are already standing there) behind skeletons.
