I played around with this spell today and found it nice in the way it provides healing. It seemed automatic if you were hit it healed. Not a random proc like many of our self healing abilities are and seemed to be more inline with how Paladin defensive healing should work. If more of our small heal abilities worked in this manner our defensive healing would be fine. As it currently is its range dependent and that's not a good thing. Stacking multiple abilities with this reflexive healing ability would create the passive healing the class lacks and be more reliable. I did find the cast time (recast if multiples) and resist were slow and poor against ToV mobs as a reference.
