The present controller method is workable, but it does feel a bit bulky and when things get hectic a bit clumsy.

It would be nice if instead of 3 lengthy action bars, we could have a Secret of Mana ring style menu system. Unlikely to happen unless the UI add-ons go to the core:

Using ps controller as an example, press L1 to bring up a ring for attack and weaponskills, L2 for other abilties, R1 for magic, R2 for items.

Of course when you change to a magic class L1 could be offensive magic, R1 healing magic etc, basically tailor it to the class or let the player name the ring categories and fit in what actions they want entirely.

Make those rings smart to re-open on a favourited action or last used action.
Forget about macro bars, allow macros to be custom made and slotted into the rings.

On another note, there seems to be a lot of redundancy in the controller config: autorun button could simply be coded to be automatic if you hold forward for 2 seconds, theres overlap between micro menu and main menu (basically UI needs streamlining and is still being worked on...), and its a bit redundant to have a specific button to view what status effects are on your character after you've played the game for over 2 hours.
