The shaman I am now more comfortable healing than dpsing with enhancement, and I don't really play with the elemental build. That's probably from endless heroics and raid healing for as long as she has. I can still pull decent heroic dps but not in the 3k range. And tho I have some elemental gear gathering dust in the bank, I just don't play with it. Mainly because I'm not a rich wow player!
And now the priest, the last of my 70+ toons is leveling. She went from 0-40 as holy, 40-70+ raiding as shadow, and 70-72 as deep discipline healing instances for guildies as they started leveling through those low areas. But now she's back to shadow and I am rediscovering just how much fun that is. Sure healing with discipline was fun, proccing bubbles around people and holy-bazzuka-ing, I mean hitting people with penance randomly in Dalaran, was fun. But somehow the quests are more entertaining from a ranged perspective, as opposed to the shaman and druid.
I guess my hybrid-ness isn't 100% since I haven't, or cannot, master all three specs of the shaman and druid, and I never claimed to be an excellent priest of any spec, but between a tank, a healer and a ranged dps I think I'll have things covered for pugging.
