I plan on trying to setup my character like this (eventually :P) so that I can be an effective healer. I actually posted something similar a few days ago about a build using Mind Flay, but figured after some of the comments that I would try to repost as just a pure healer. What I don't know (since there is no FAQ for priests other than Shadow) is which talents are actually the most effective to take. I figured all the spirit boosters and spirit buffs would be a nice way to buff up my healing (I may even be Human just for the spirit buff, even though I'll lose Symbol of Hope and Fear Ward, but is it really worth it?) but I'm not sure if they are actually better than other talents or not.
Anyway, any advice is more than appreciated :)
