Sometimes you get real beautiful PuG's.
Halls of Lightning
He has an aggro-range of miles, so by all means healer, go stand there, and pull him. Oh, you only have 5% health left, while the rest needs healing due to Whirlwind... luckily I have lay on hands.
Just after that:
Slags, run through them, round them up, and to be sure, Divine Protection... and yes mage, healers and DK, by all means stand right besides me.... rez-rez-rez....
Just after second boss:
Healer is Shammie, where are my Tremors???
You know dispers? Well, healer+DK, by all means, don't run... activate DP, use trinket, use Nightmare Seed (yes, I still have some), kill boss. Rez...rez.. oh healer already ran in.
Oh yes healer+mage, by no means stand close.... LoH the healer, mage dead, healer drops group before ressing, probably because of the 'WTF no heals' from the mage.
Well, at least I was not bored :)
