[Priest] Raid Gear for Healing PvP/PvP Gear for Raid Healing

[Phyle]

Hey, I hope the Question was not asked already ...

When I am active in Raids as Holy Priest it will be fun to heal in PvP sometimes or help as healer in World PvP. Is there a level of Gear where you do not need to farm the PvP sets (rare and epic) anymore, because the T-Set is better than them?
Or is PvP gear needed, because of the high amount of Stamina to have a chance to be not 0.5 second one shot?

On the other hand is there a level of Gear where the PvP gear (rare and epic again) is worse than a T-Set?
Is it even possible to use rare or epic PvP gear Sets, or pieces of them, as pre Raid gear because of the high amount of stamina?

PS: Please report spelling/grammar mistakes, english is second language for me .

My priest friend was complaining the other day that he felt less sturdy in Truefaith Vestments than the rank 10 robe. I don't know anything about that though, I just cast frost bolt.
