I was falling over my own hands at first in this game, the easiest (and free) solution is to set the movement keybinds to the numbers pad, I left the normal ones in so I have 2 sets of movement keys which means I can free either hand when I need to.

I have 7 and 9 as my strafe buttons and 8,4,5, and 6 as my direction buttons, with the * key as my auto run. That way in a fight I can do movement with my right hand and skills/abilities with my left.
