I don't play Holy a lot, but do you honestly ever use Heal while in Sanctuary? That seems a bit silly to do so with 10 second CD on Chakras so you can have an instant cast that heals just as much as Heal does. Healing trinket looks interesting and I guess I can spam PW:S even more and take even less spirit than I do now. The healing ring looks interesting as well. I wonder if that's why they dropped Amplify Magic since healers can just RNG proc themselves to do 10% more healing.
Current Disc 2pc and 4pc look interesting. 4pc makes me feel like a MW channeling Soothing Mist though.
