I hate those controller layouts. I've thought about design choices and layout before. Can we individually change what buttons do what? That would be the best way to deal with these setups. Imagine a world where the B button was still melee, the left bumper button was to change grenades and right bumper was to use your special ability. I think it would be way better than your current layout. I mean come on...a whole face button to change grenade types? ARE YOU INSANE?
