Sloppy Gruul Kill from my perspective.
http://www.twitch.tv/reteponj/c/6099376 After struggling with healer mana a couple times, we really need to time our channeled potions to a slice where the raid is fairly stable. The boss won't do his line attack while he's slicing so there's no chance we will have to cut them short.
Also, should probably not stand directly inside of the boss for no reason. >.>
