This may not have helped the problem, but to diversify a bit, I really think they should have made Machinist deal blunt damage like many people speculated they would when it was announced. That way Dragoon wouldn't have the monopoly on synergy. At least Monk/Mch would be competitive with Dragoon/Bard. However, no matter how any of this shakes out, there will always be a meta. It'll just be different if Dragoon loses Disembowel.
