"Best" mean "best output of damage" or "best in doing his job"? For the first, i sincerely don't know, maybe blm, maybe drg. For the second, i must admit that arc and brd are pretty amazing, simply for the "ranged attack + mobility" thing. A BRD can run around away from mob range, kiting while doing his dps job, still doing pretty damage while alive, take less hits, and so doing his job "better". So, if we are arguing in a perfect world where dps take no hits, go with blm and drg/mnk. In a normal world when you must move + damage move + damage and again move + damage, choose BRD.
