I levelled to 41 as holy. It got real slow- but I didn't have a 70 alliance on that server, so my gear suffered. I went shadow up to 57, now I'm back to holy. I mentioned this in general forums, but holy just feels "right" to me. I know warcraft lore has dark shadow priests, but I don't want to be one. I want to be a healer type, and help people. I still don't have a 70 or 80 alliance, but my 69 ret pally had 2 gathering professions, so I could get a little better gear off AH. Soon I'll be in outlands anyways where quest rewards are actually decent (compared to old world quest rewards which are largely crap).
I considered going disc, but I just don't know much about it. I am thinking about putting about 10 points into it though. I also have 5 in spirit tap (and imp.), I feel this is necessary to avoid drinking all the time (or not going oom when you get 2 adds). And I also have the smite talents, most all other talents are things to improve healing (though some improve damage as well).
I'm also doing it for the challenge, not just because it feels right. I had one girl said she couldn't level in outlands solo as holy (and went shadow for the xp until 80). I don't care for this girl very much, so I just want to prove (to myself at least) that it can be done without too much trouble.
