PC players using a controller can. I think aim assist is different for PC and console. Ask console players, the overwhelming response is that it's barely noticeable or it's so bad they turned it off. Every PC player I've seen talk about plugging in a controller says they get crazy snap-to-target aim assist. So, either aim assist is so broken that it works for some console players but not all, or it works differently across PC and console.
If you're getting beamed by console players, they're most likely using a cronus. I turned cross-play off (I know you guys can't which sucks) and immediately the gunfights felt better. But there's still cheaters using cronus. Every few matches there's some guy with 100+ kills, who every time you face him, doesn't miss a shot from any distance before you can even ads.
