I think the biggest problem with Holy is that absorbs are far too powerful as they stand. Something needs to be done because Disc basically makes healing for all the other classes healing with one on their team less fun. They do so much by themselves that it's just demoralizing to the other healers. Holy suffers the most simply because it's the same class. Why be a Holy Priest who's got to be at the absolute top of his game every second when you can do less work and perform just as well or better by spec'ing Disc. Also, Chakra sucks as it is. They need to bake the +healing into the Holy spec and simply make Chakra about efficiency and flavour. Significantly lowering the cooldown of Chakra too would be lovely as well. Maybe even change PoM to be more like the proc from the talent where instead of waiting for damage to jump it starts bouncing the second you cast it.
