This is a great addon. It allows all classes that buff the ability to buff without guessing who has one, and who doesn't. One thing that makes it even better is the Blessing Manager. It communicates with Pally Power, and in addition, it will auto-assign who does what buff based upon a scan it does of specs to see who has improved blessings and so forth. So, a Holy Paladin isn't being assigned to bless Might if there is a Ret Paladin in the raid. A great addon.
