I still have my priest - which was my main from vanilla through wrath - sitting on the shelfs waiting to hit 85, and recently thought about leveling her up for pvp, mostly battleground, purposes. I always loved shadow but from time to time liked to heal as well, especially in pvp.
So, is there a viable way to only get 1 PVP set and being able to use it for both healing and shadow battleground play? I imagine getting the spirit set would be best? Or the crit set and reforging to spirit for healing? Or a mix of both?
