I proposed this in another thread, but I'd like to repeat it here. 5/5 Revitalize for Paladin outclasses any other talent. Whether you're leading the charge in arena or dropping him on some troops for emergency CC, instant damage mitigation is the way to go.
I agree. Revitalize is most often the best talent for arena. And that's true for paladin too, it dies often before it can start using shield. For raid, berserk or survival type talent give it better chance to survive the whole battle.
Thanks for pointing that out.
