What if they changed Monk to something akin to SAM mixed with Zell's Limit System from FF8.

Remove GL or make it a always on trait. If removed make all MNK's GCDs 1 or 1.5s unaffected by skillspeed.
Remove Fist of Fire, Earth, and Wind.
Change Meditation completely to be like that of Iaijutsu but instead of making sens you perform combos with your GCDs to do heavy hitting moves. For Example one combo could be Bootshine > Bootshine > True Strike = Dolphin Blow. Kind of more like the Mudra system I guess but have it so that one Heavy Hitting move would empower the other or, make it so that one heavy hitting move starts the combo of another move similar to Legaia 2. For Example if Bootshine > Bootshine > True Strike = Dolphin Blow and Bootshine > True Strike > Snap Punch = Meteo Rain then you could do Bootshine > Bootshine > True Strike > Dolphin Bow > True Strike > Snap Punch > Meteo Rain.
