Nothing changed from what I can find with the CataBuild 12759; however, they did release the interface for how a paladin’s holy power is monitored. I was honestly expecting a combo point bubble but alas, we get something aesthetically cool!
Remember that as a healadin, our major source of holy power generation (from what I can tell not being in beta) is from the Tier 6 talent Tower of Radiance and healing our beaconed target. We also have a new spell in Cataclysm, Word of Glory, that will heal the target and consume the holy power and is free of mana. I have covered the basics of Holy Power and sneak peeks that were revealed on its uses for all classes already, so I won’t go much further with that. I am just loving the runic bar!
