We had Nether, Slate and time warden also.
3 tanks - Prot Pali, Bear, DK
3 heals - Shaman + Druid tank heals - holy priest raid.
4 dps - Enh Sham, Rogue, Ret, Hunter (our dps makeup was not an issue)
We didn't get the boss down yet, but this is where we are upto.
You have to release Nether immediately because of the speed buff he gives the boss. If you dont the healing debuff stacks so fast it will be a wipe in under a minute. You have to release the time warden otherwise the fireballs will wipe you due to exceessive raid dmg.
We had 1 tank take Nether, Another take the boss and another pull time warden.
Pop Lust and burn Nether, while the tanks switch as required on time and halfass.
Nether dropped quickly, then we get the free tank from Nether to release Slate while DPS burn down Time Warden.
Once time warden was down we were switching to the boss and hoping to beat the enrage timer. I am not sure if this is possible with 4 dps. 3 of us were pulling 23k each and the ret was pulling 18k.
What was wiping us was the shockwaves and the tanks going down as a result.
So questions
Do we need the dmg buff from nether, slate and time in order to beat the enrage?
How is the best way to survive the shockwaves? I can't recall if you can interupt it so it doesn't happen? With enh sham, rogue on the boss that would not be hard to stop if that is possible.
