I can literally hold down the thumbstick, or even push it down while it's still in the deadzone enough so that there's no way it could possibly be going up, and it still goes up. This is pissing me off beyond belief. I've missed revive snipes because the -blam!-ing thumbsticks decides to go up at the last second. Even when im holding it down, it drifts. I'd have no problem with it if it didn't do it while i was holding it down, but it does it anyways. Help??
