Let's put it this way:
I'm no pro but if I could play against myself, my 20 years of controller experience (with aim assist cause it was always there) would lose a duel against my 2 years of mouse and keyboard experience every, single, time.
Am I the only one impressed that controller players are even on the pro circuit in 2021?
Explain to me like I'm 5 how aim assist is SO good, that their skill on a controller is nulified because of it.
I'm no pro but I've used the same aim assist, and I am far worse with that than I am with mouse and keyboard. So yea go ahead, use the suboptimal method all you want. If you get that good on a controller (even with aim assist) you deserve it lol
