Most jobs it’s a insufferably adjustment as you get traits and skills you have to read carefully then piece out your rotations accordingly

Having said that MCH has the least amount of skills in the game, the easiest job in the game and the one with the least amount of confusing or punishing mechs within its kit. It also miraculously doesn’t evolve much past 50 besides 1-2 skills so if you got it’s 50 rotation down you essentially got its 80 rotation down as it gets nothing but Aoe Fodder or “upgrades” ie like Broil or Aero.

If Que times are a issue I suggest call your FC for help, or do fates while you wait as fates are swarmed nowadays thanks to events. But honestly if you could Care less about the Job quests MCH is the least harmful to Level skip. Any other job would be a nightmare to relearn with 18+ skills everywhere but thankfully MCH is a subpar job
