Disc priest by far my friend. On my disc priest I use this spec: http://us.battle.net/wow/en/characte...talent/primary I have a cast sequence macro that casts Holy Fire and Smite constantly and ocassionally I have to rebubble/penance my tank. Its so easy running heroics/non-heroics. I don't think I have ever casted heal / Greater heal. Between the damage healing, shields and pennance not to mention the occasional flash I have no problems. One suggestion, there are two glyphs I am not currently using but I do use when not doing pvp, glyph of divine accuracy because when smite or HF misses your tank gets no heal and glyph of smite which incrases damage making the heal larger. Prayer of Healing glyph is the last one that is must have because the Hot It leaves behind is amazing.
