Huh? Are you responding to the correct person? Did I say or even imply that only controller players cheat? I don't feel like I did. Regardless of developers giving only one input assist, that doesn't make it fair, or the right thing to do. It's for sales and has nothing to do with fairness. It's a lazy design approach that only the most unimaginative studios use.
I will however, keep advocating for shooters to stop implementing assist for just controller players. Imagine having to aim in an FPS game, the shock, the horror!
