I leveled a new priest just because it was a class I hadn't used previously. It's been immensely fun! I was all about Disc until they applied the bubble mana hit. Since then, I've switched to Holy, and found its even more fun. The vast number of heals, the crazy combat regen, and still being able to use a decent bubble off the bat is really a good time. I agree that the multiple hotfixes are getting to be a bit much, but since swapping to Holy I can't imagine switching back.
