First off, sorry if this has been posted before. It has just been so beneficial thought I'd make sure other priests see it.
General tips / tricks / idea for Discipline Priests in arenas. Jeck did a very nice job with these videos. Easy to follow, goes step by step. Hope this offers as much to other priests as it did to me.
EDIT: Maybe should've tagged this as "Arena Healers" or "Arena Casters".. While the videos are Priest PoV and pretty Priest oriented, there are a lot of helpful tips for all healers. And even some pretty useful stuff for casters in general.
