I went through the same crap with MCH back in the day when the job wasnt lobotomized.

The MSQ got trimmed and shouldnt take too long to get to "Before the Dawn" no other classes exist anymore so it starts at 30 like every other job while SB jobs start at 50 and for the dummest reasons SHB start at 60 which arent Progression gated so you can over level to 60 to get them but makes those jobs bad as most of the instances shrinks ur tool kit up until the climax.
