I like the idea of using WASD and the arrow keys, but they were a bit counterintuitive. 1) On keyboard and mouse, WASD are usually the default movement keys and 2) in a two joystick format the left joystick (usually) is mapped to move while the right is mapped to look around. That being said, I know some left-handed people choose to go with a southpaw config, so having the option to switch between WASD/Move and WASD/Look would be awesome. That way people could pick what's more intuitive to them.
