First off, sorry I don't have any logs for you.
We're having issue on Un'Sok the Amber Shaper.
10 man normal mode.
Thought I'd edit this quickly to throw in our comp of last night.
Melee: Rogue, Death Knight
Ranged: SPriest, Ele [me], Mage
Healer: Druid, Priest, Druid/Priest [he switched]
Ranged kill Ambers, then Constructs then nuke boss.
We do the same, but instead of nuking the boss, we nuke the big construct.
We died shortly after entering it.
I noticed some of our people not interrupting their explosions, but that shouldn't be all there is too it.
