Honestly, the less you listen to people complaining about how you play games online, the better. Picture yourself as a person who prides themselves on being able to twitch around with their mouse, and gets a warm fuzzy ego boost when they pull a massive flick shot off. Now imagine, after having felt really good about doing well, you learn that some doing better than you is using a *gasp* inferior input method. Simply put, it would cause your ego to go into defensive mode.
Titanfall isn't a competitive game. It has a gun that aims for the player, a skill that lets players see through walls, and a burn card called "map hack." Even if it was though, you still just plain old shouldn't worry about cheating because of the equipment you use. Why?
Amazing, but according to the person that called you out on titanfall, he is also "cheating." Every single player who plays at LAN in Counter Strike either uses a 120/144hz monitor and almost all of them use a high performance optical mouse with a higher perfect control speed than the average consumer mouse. One could make the argument that anyone could potentially buy a high refresh rate gaming monitor or gaming mouse, but not everyone has hundreds of dollars spend on something for a slight edge in competition. Furthermore, while good players would always be good regardless of the equipment they use, high refresh rates invariably increase hand eye coordination and a sub-par mouse sensor simply can't keep up with the mouse movement speeds required for low sensitivity play.
Now, I'd definitely hate the idea of auto aim being made available in a game like Counter Strike simply because it might mess with the skill ceiling, but if it were present for everyone, it's not cheating. People ***** about the auto sniper and the p90 all of the time, but that doesn't stop players like n0thing or get_right from using them.
