Suggested improvement for PC controller support

Currently as it stands the biggest flaw is the aiming and movement both being mapped to one analogue stick which makes it impossible to switch your target while still standing in place making it almost impossible to stand in place while your casting/attacking. This could be improved by either mapping aiming to the right stick or more drastically by removing the ability to assign abilities to hotkeys on the fly which would free up the r3/l3 buttons which could then be used for a new hold position command.
