Gruul was a fun fight. Between Quantams mana regen, my totems, and my crazy crit chance (45%) due to my totems and walls moonkin buff (crit = clearcast) I coudn't spend my mana faster than I was getting it back. I started throwing in chain lightning (Costs a bunch of mana, but it's a faster cast) and earthshocks. But i coudln't catch mordos on the threat meter. Looking forward to doing this again!
