Designed to help controller players with aiming. Without aim assist, aiming accurately on controller would be downright
impossible due to the nature of deadzones, analog sticks, etc.
Aim assist is controversial as
bad kbm players find it difficult to admit that their aim isn't at good as they think it is, and that some controller
player aiming with a joystick
beat them in a
1v1. So instead of trying to improve their aim, they say that they lost because aim assist.
It is common for these kbm players to spread misinformation about aim assist to justify their losing to controller players, such as aim assist is 'aimbot', 'reduces recoil', 'reduces bloom', and 'increases hipfire accuracy'. When these are all simply not true.
