why should it matter if its hard to play 4-5 melee when paladins start with a full mana bar charge unlike rogues that have to build up combo points and manipulate with stuns and positioning and warriors that have to build up rage through swings. Ret paladins only have to be in your range that one brief instant to get their attack combo off on you and the top tier retribution attack is an aoe whirlwind of nastiness.
