Minuet should've been a song with a cast time that drains MP and buffs the bard until MP is drained or the song is canceled. Like Foe, but for self. It would've been 100% in line with the established play style, wouldn't have gotten in the way of using oGCD and also would've given some new choices to make in the midst of combat. Am I going to be supporting the party any time soon? Will Foe increase party dps more than Minuet? Will this fight last long enough to justify the cast time? And if they wanted to enforce standing still, they could have made the song drain double MP when on the move.

MCH could stay the way it is in my opinion. Its other mechanics allow instant casts while keeping the buff, and I would prefer the job being different from bard if bard is given back its original game play.
