Me and my guild progressed fast thought the first 4 bosses (2-3 Shottet them), but we got big problems on Anub Heroic mode, we did like 15 attemts, but wipe because there is no Ice left.
We also tried it with 1 Tank, 2 Healers and 7 DD's too (at begining with 3 heal, 2 tanks), but there was not much success.
Any advices/tips?
