Aim assist should NEVER be in a competitive game. EVER. Kind of just defeats the whole competitive point. I'm wonderful at aiming. However, you add the "snap" effect with an aim assist, and suddenly where I'm trying to aim is past because it snapped while I was dragging the reticle. It's dumb. Then you get to the aim acceleration, where I know it's going to slow down my aiming seemingly at random, so I try to adjust for that, and end up aiming past the target or just before. If people can't learn how to aim without an assist, then they should play without one so they can. It's ridiculous how games keep catering to people who think they need an aim assist. At the very least, put an option to turn it off. Go a step further, and include separate game modes where aim assist is off for everyone in that playlist or server. I had a similar issue with one of the Call of Dutys (might be a different game, but pretty sure it was CoD), where you could literally just sit holding no buttons, and if an enemy ran NEAR the center of your sights, the game would try to "correct" the aiming that you weren't even doing.
