I can see how just straight taking it off forbearance might be a balance problem for PVP as other specs... if that is the problem, make it talented deep in the tree:
Guarded by the light
Reduces spell damage taken by 3/6% and gives a 50/100% chance to refresh the duration of your divine plea when you hit an enemy. In addition, your Divine Plea spell is 100% less likely to be dispelled and Divine Protection no longer is affected by or causes Forbearance.
I don't care what you have to do to make prothealing in arenas not OP with the change (TbtL causes crit heals to apply a stacking -10% resil debuff?), but taking away pallytanks' ability to reliably use their ONLY cooldown when THEY choose is not a good solution.
