Hadn't really thought about it, because: 1) It's unlikely any substantive changes will occur until 7.1; 2) I'd be surprised if any jobs get one new button, let alone 3 or 4.

I rarely play the jobs you mention, but the SCH and AST changes look to me like they'd require pretty significant reciprocal balance for other jobs because of the synergy of multi-SCH and DRK+AST.
