holy power is fine, as having a rotation of hard hitting abilities is better than a seal of casino (so long as blizzard doesn't want mechanics that add extra attack swings) but the art of war and blade of justice should probably hit and/or scale better amongst other things to help deal with the sluggishness of it currently; simple solution would be make it holy dmg all the time
auras and seals, sure; GREAT start. but as i iterated before, they need to be thrown on the drawing board. a return to passive cast and forget wont make the class more fun or interesting.
