Hey guys, I am planning to venture into a main build for pvp, and I was thinking about either going deep into holy/disc. If I were to go deep into either of those builds, leaving either or with nothing, would this hinder my ability to be a healer in raid situations?

The predominant priest build is 28/33 or a variation thereof. The reasons are simple. You need improved mana burn. Period. It is one of the best PvP talents in the game. You also need all the defensive talents you can get, because odds are you will be focus fired. Combine that with the fact that the high-end single-point talents in holy and discipline are crap and your choices of build are pretty much made for you. Deep holy or deep discipline builds do not perform nearly as well in arena because each is missing some key talents without getting much in return.

Such a build would not be optimal for raiding, but you can probably get by if you are skilled and your guild is not too hardcore.

Whether it's going to hurt you depends on how well you can handle the healing now and how exactly you spec. Looking at your talents you're only missing Spell Warding, Blessed Resilience, Martyrdom and Improved Mana Burn from the "must have" talents. Shifting a few points you could easily get something like http://www.wowhead.com/?talent=bxMrzhMZfVxccMsVuA which shouldn't affect your raid healing too much. It gets a little trickier to keep the raid talents if you shoot for Focused Power though. http://www.wowhead.com/?talent=dxMRuhgzMZfVxccMRV0h is an example that's closeish to what you have now, and as you can see you have to drop the deep holy talents to get it.
