Considering this could really only cause consistent trouble with paladin tanks casting it on themselves, I've already made my peace with the change since I rarely tank.
The only thing I've been wondering is, let's assume a paladin tank uses LoH on himself during a fight, gaining Forbearance. Before Forbearance wears off would it still be possible for another paladin to cast it on that same tank, since it wouldn't cause the debuff?
Logically you'd think there wouldn't be any cross-debuff interference to prevent it, but I'm just thinking aloud. Any thoughts?
