I don't think the problem with RNG is a lack of damage. We're relatively on par (despite paying). We still can get hate just like every other DD.
Problem is, when RNG gets hate, it screws everyone else including the RNG. Now the RNG's distance nerf comes into play. Now every other melee DD has missed his WS as the mob comes raging after you. Now every mage is muttering "Gawd damm RNG!" as AoE moves towards them and they have to pump out a ton of Cure V's to save your ass.
Until the enmity formula is changed, the bottom line is that a RNG has to hold back to keep everyone happy and that will always nerf your parse.
