The main issue mch has (aside from playstyle being very difficult and ping reliant) lays more in brd just being the superior choice, while also being substantially easier to play.

Adjusting mch to be more comfortable to properly play is certainly a must, but I don't think they should be buffed up to where brd currently is. Rather, brd needs to be brought down closer to mch levels of party dps contribution.

Why? Because if mch got boosted to being a competitive option against where bard currently is, mch will not be competing with bard. Casters will go back to not being in parties again. nin/drg/brd/mch double ranged, infinite synergy, max dps, along with double refresh, double palisade, double every bs range utility will reign again as the uncontested best party comp, outside of a fight that would absolutely require a caster lb3. I don't want to go through that again.

A range dps will always be in a party comp, regardless of their contribution in regards to the melee, or a caster, solely do to refresh. The easiest course of action that wouldn't result in double range being the absolute best static option would be to reduce bard's power a bit so they have to compete against another job.
