Hi, was just about to go to bed but saw this got quite a few posts really quickly (ty for them btw) so thought I'd just clear a few things up.
Basically my job involves getting the Mana Void down to a decently low health (but not killing it, which probably explains the low SS damage perhaps (trying for the most part to avoid DoTs)) and then obviously killing the oozes and then the boss.
I think I have been not AoE'ing the adds enough though, I can see that now. I've probably been relying too much on other people to do that and been focusing on the boss primarilly too much, so thanks for that and that's something I'll certainly try to do more of next time we try it.
Anyway going to bed now and thanks for the help so far
