Holy priests, rejoice!
Chakra: Sanctuary was reworked - Each heal cast while this Chakra is active reduces the remaining cooldown of your Circle of Healing spell by 0.5 sec. Transforms your Holy Word: Chastise spell into Holy Word: Sanctuary.
Chakra: Serenity was reworked - Causes your single-target healing spells to refresh the duration of your Renew on the target. Transforms your Holy Word: Chastise spell into Holy Word: Serenity.
Let's hope these stick. Increased spell power coefficients are likely incoming to make up for the -25% due to the lack of chakra.
