Black Mage and Samurai deserve to be the top 2's because they don't bring anything else to the table other than their personal damage.
Said that, of that "lower dps tier" starting from DNC downwards, MCH should be at that top, given it's the selfish dpser of that niche.

I don't see anything wrong with the 6.0.8 buffs other than MNK being unecessary and MCH being lackluster.
