Ok kiddos, gather round. Just because your chosen input method is crap does not mean they have to nerf others to keep up with the crappiness of yours. The fix is to remove aim assist. If you are good with controller, nobody can take that away from you. If you are crap with both input methods and crutch on the aim assist, well then I guess you come in here and whine when we call foul.
Put it like this, I want to play multiplayer shooters with a super scope 6. Should Respawn, Activision and the like be responsible for making my chosen crap input method competitive!? Of course not! This would inevitably leave me with either a crap experience (which it should), or I will be OP because of the "help".
Aim assist is crap and has no place in competitive shooters.
