It is mentioned here for an odd amount of AP to be used for bonus move, and that everyone gets the bonus move perk.
Keep the first part about odd agility, but don't give bonus move freely. Instead expand what the "bonus move" AP can be used for (I'm not sure if this is possible from a coding perspective)
-World interaction (pickup/drop/use object)
-Item use (careful with stim SPAM)
basically, allow its use for anything except attacking, although some further restrictions would be reasonable for combat situations.
