Lots of people gonna hate this, but here goes. Give MCH a third mechanical pet... the automaton like pup had in XI. Keep it simple, weak or even no attack. Have it emit a pulse or something to generate emnity. Have it be a lil different than the turrets in that a small amount of the hate the mch generates also goes to the automaton, also it can move around. I suggested little or no damage bc even if MCH is a weak dps, it is still a dps, and I would want this so MCH could pseudo tank like SMN can with Titan. Slightly higher hp and def than turrets, and something like promote makes it switch between single target hate generation to aoe hate generation, and hypercharge makes it get slight defense boost and maybe slight regen or something. All other class/job tanking support abilities would be able to work on it, i.e. eye for an eye, cure, regen, protect, stoneskin, ninjas hate managing abilities, so on and so forth.
