The addition of sprint as a default ability was an excellent choice, but it seems like the controls schemes are all out of whack now. For me, boxer was the only way to play halo. I like to get in close and use a lot of melee and not a lot of grenades, but for some reason the boxer button layout moves sprint to the B button which makes it almost entirely useless. Please move it back to the left thumbstick where it belongs. Or better yet, let me make my own button layout.
