Hi.
MCH have the less number of active during a fight, you can do savage only w/ 10 actives. (11 with pot and 12 with Tactician) Pretty easy so, even on controller. Also, he's the only one DPS didn't have a dash (with Summoner)

A suggestion : GiveDashToMch. One for going nearby enemy like a grapple-gun, one explosive shot bring back ya' for 5-10 yalms. Can enter easily on the opener.

Cya.
