Some people like it, I personally don't. What is aim acceleration? When you turn to the right or left, you turn faster the longer you continue your turn. I hate it and find it difficult to make precise shots with. It actually isn't too bad in this game but I would like an option to turn it off if that is possible. I know some other shooters give you the option (Planetside 2, Blacklight). I think it would make the game more enjoyable for me.
