This trinket may be cute and all, but I'm afraid, from what I saw personally, that it may not be the best for a holy pally. Since it actually removes blessing of light from the affected target to put the healing buff :/. I like way more my +120 heal to flash and +380 to holy light than a group wide +100, especially when there are other holy pallies healing that one target

Edit : well, my bad, 150, since it's 30 not 20 :p. Still prefer blessing
