On Eonar - US here and it seems as if my heals have increased and I actually find it more efficient. I don't have to struggle when trying to get my groups' health up after say, an AoE damage or something and its easier to heal up bums who stand in fire before I yell "get out of the fire!".

I critted a 78k Greater Healing wave the other day without any other external procs besides Unleash Elements. Its either RNG or the buff taking into effect because I haven't see a Greater Healing crit for that high in this expansion.
