How does your shaman maintain such high mana throughout those long fights? I run Pally, Priest, 3xShaman, and the shamans all have pretty similar gear to yours but they run low on mana by the end of the fights.

I had another blast at Patchwerk last night and got him to 100-150k each time, my dps just isn't quite there - really bloody frustrating! Managed Noth one shot thanks to your vid though, I'd not attempted him before. Thanks!
