Stiffolous

I wish there was a way to change the Universal Reclaimer button layout slightly. I like it except one thing, B is crouch and left stick does nothing in the older titles. When I hold B to crouch I am not able to look around at the same time. Also crouch jumping is more difficult, and in halo 2 and 3 crouch jumping is crucial. I would like the left stick to crouch and the B button to be sprint in halo 4 and nothing in halo 2. please just allow us to customize the layout a little more.
