Based upon my observation I think AST, NIN, SAM need more tweaking. I've heard from plenty of former NIN players of their issues, but the job is getting better. Same with AST. GNB could at least have the issue with Superbolide addressed. Naturally, DNC will be receiving constant tweaking during the expansion.

As a RDM main, I will say that Reprise is terribly underwhelming, but it's a job that I've accepted as "used during progression but not during clears".
