Yeah but then you still can't just quick tap the R1/RB button on the controller to flcik really quickly between hotbars. I have managed to fit every action for all the DoW classes into two which makes it very simple to just flick.

SCH/SMN seem to have so many abilities that it might push to a 3rd and a pet hotbar on top of that means limiting it to two can't be done to quickly flick between.
