I Have had two Garrosh Normal kills so far, one on 10-man and one on 25-man. Loads of wipes. From looking at my my logs it seems the biggest difference between the kills and the wipes are DPS.
Question: Since transition to 2nd phase is based on health percentage and not a timer, does DPS during phase 1 really matter? Since there never semes to be hard enrage issues, is it really no point in applying tactics or using cooldowns to maximise phase 1 DPS? The big DPS race to kill him before the empowered abilities overwhelms the raid starts as he goes into 2nd phase, right?
