An hour an a half I spent organising a PUG for Zul Gurub.
Before you say it - stfu and listen.
Logically, it should work - everyone is lv60, and is bound to have enough decent blues to be able to compete, logically anyway. Our MT's were kitted out in full Wrath, but we STILL couldn't beat that priest with the secondary boss and the two elite tigers guarding them.
What the fuck gives? LOGICALLY it should work, right? What makes a guild raid so much more efficient? Purely the fact that everyone listens to the leader? What else could there be?
The raid fell apart after two wipes. Wankers.
