Gregg, my fellow paladin columnist, and I like to make jokes about Blizzard's strategy for naming paladin abilities. Holy This, Something Retribution, and Divine That. Their creativity can only stretch so far, as paladins have a very defined set of lore, and there are only so many words that relate to their holy upbringing. Paladins have the additional downside of being a hybrid class, and so this means that the number of available ability names depletes faster than ever.
Blizzard changed Healing Hands' name to Holy Radiance, which is probably a great move, considering that we already had a heal named Lay on Hands. Duplicate names didn't stop Blizzard's team from christening our second AoE heal with the same name as one of the game's most prestigious achievements and a title, Light of Dawn. Light of Dawn itself isn't safe from the instability, either. Its function went from a simple heal that was boosted by holy power, to a regular AoE heal that had no target cap, and it has even been changed again. The new version of Light of Dawn is a smart heal that consumes only holy power, which completely changes its functionality and usefulness.
