Given what all a DNC can do I can wholeheartedly say they will have to be the lowest DPS in the game. That being said I do think they will be mandatory for parse runs to chase those oranges.

What gets me is that SE said they want to do away with preconceived mandatory classes and lower job synergy, but then release DNC???

Anywho just spit balling here but I think the new meta comp will be something along the lines of GUN/PLD/SCH/AST/DNC/some other 3 not sure yet.
