I have just reached level 30 on my WoW Priest and I am wondering what two talent specs. that I should do. Up to now, I have been a Disc. Priest and I mainly heal (I have only DPS in dungeons a few times). I only ever do dungeons (when I heal) or PvE, I rarley do PvP as I am not very good at it. I am wondering though, what two Talent Builds should I do if I mainly heal in dungeons and PvE, Disc. and Holy is the best healing, but should I go with Shadow and something else incase I need to do DPS? Thanks a lot for answering!

I say you keep your main as disc healing. Your second could be also disc, but have more of a PvP build for those times you decide to do that. My website is in the sources. It isn't related but you should check it out.

Shadow is for damage. Damage = good. Damage = DPS + Leveling + Raiding + PVP. Holy = Healing = Raids PVP. Shadow should be for leveling and doing damage. Your gonna have a tough time later leveling if your not shadow unless you gonna a friend to play with at all times. Level 30 though you really shouldn't be worrying about getting into dungeons at that level seeing as it's quicker to avoid them all together up to the level cap. Downloading some mods should help you heal just make sure to get them from legit sites.
