You would also need a way to understand how many AP you're about to use to move where you want to move using your keyboard for movement....which doesn't seem to me to be intuitive...

I like how it is and obviously would reject this change request to be the default standard.
But to give you an option to change your keys and allow you to move with your keyboard...if it's doable and your not the only one requesting that.... I'm just not sure how many people would use that feature though
