The arcanes are right... melee DPS really isn't needed. Now I know, I'm a melee only player and I had a difficult time coming to grips with this factoid. But after several raids/quests later I think I'm slowly beginning to realize what everyone else already realizes....melees are effectively outgunned in the damage department.
What melees are good at and are probably only good at right now is tanking. Especially, after the PrE's got fixed and a few nice shields/weapons came out. But yah, Arcanes win in damage.
