Well, those are some interesting points. I would counter with if this is driven principally by console players and the UI- why not express it that way, as you have above, maybe it's possible to introduce some options in the UI specifically for controller players?

I can't comment on console, on PC there are ways to make (for example) selecting the target/playing your cards much easier so that you can switch between players and the boss- however on PC I definitely went through a lot of setup on the basic UI.

because I would prefer that changes are introduced based upon improving the job design, if at all possible, and not due to what may be a poor use of system controls/UI.
