I've got a Disc specced priest that will be hitting 58 any minute now. Then its a matter of waking up tomorrow and blasting my way to 60. Right now, my mana regen is great. I don't know if its because of gear or if its spirit tap doing it, but I cannot remember the last time I ran out of mana. I burned down an elite 2 levels above me in Winterspring without going below half as well.
My question is - stick with Spirit Tap for leveling, or repsec for Penance? I want to run instances as much as possible, so I'm sure Penance would be useful, but on the other hand, BC instances are probably a pain in the *** to group. What do you folks think? You are much more wise than myself in the ways of the Priest!
