You neglect to metion how much more control one gets from using the mouse, especially a mouse with a very high DPI.
Just remove mouse control and everything is fine. Don't have a joystick? Keyboard control is available.
What does DPI have to do with anything? Nobody games using high DPI, it's the opposite of precise. My mouse can go up to 12,000 DPI and I have it set to a whopping 500 for elite.
