For AoE there is no question that Blm is tops. If you are questioning that you are very confused. Smn is likely second in AoE. Followed by Bard, Monk and Drg that all do about the same damage in AoE (read their abilities).

For single target its almost certainly Smn and Mnk on top followed by everyone else. The longer fights go on the better these two get.

Overall the balance is pretty good and SE has already pointed out issues with melee that they are planning to fix.
