I often find myself fighting the controls in PSO2, so I thought I'd propose a new layout. The shoulder buttons, when held down or toggled, swap to the weapon and assigns a set of skills to buttons X, Y, A and B. When not toggled or held down, the equipped weapon does not change, and the skills are replaced with basic actions.
This would allow for access to 12 actions at any time, and quickly toggle between subpalettes using up/down without having to hit a button afterwards.
I think this alone would greatly improve my enjoyment of PSO2. What do you think?
