my guild on the pvp server killed him in about 2:40mins we did not worry about any adds that popped just full burned tarniax we were a qeynos guild so we did not even have the huge debuffs.. group cures and fulll burn is the most important thing i think our highest dps parse was only 600 which i dont even think is much
we had 3 tanks and a few swashys or wizards tanked for about 15seconds
