Its an aggro fight. And the problem is from what I can tell, you build up aggro all throughout phase 1 and 2, and if you dotn get fire balled in pahase 2, shes bound to unload on you in pahse 3. Huntards can wipe aggro, not sure about healers though. But whenever we failed was always in pahse 3, her getting turned and wiping 1/2 or 3/4 of the raid. Or the tank not geting aggro right away when she lands and she proceeds to pick off 1/2 the raid before the tank can snap that aggro. That or just getitng hit by the breath in PH2 and wiping a 1/4 of the raid lol, that one is always fun.
