I played for roughly a year with an xbox 360 controller because I didn't have a desk or a mouse or even a legit computer. While obviously keyboard and mouse is a better choice, I was able to play legitimately. T4 in CTF, bounce between T2/3 in CA. Maxed out LG at about 22-25. I could move significantly better than most T2 players. No doubt kbm is superior, but I beat many kbm players 1v1 with my gamepad.
