You're doing it for levels and ED's for Melee Power.
There should be the same or similar addition to Ranged Power. Just because Monkchers are good in LD and Fury doesn't mean they should be terrible in literally every other destiny including Shiradi. In fact, that's the argument for why you need to add Ranged Power to most destinies and to Epic Levels.
Would love to hear relevant arguments why this is not true.
