Understandably so, because people can't aim with that thing. (it's a dumb input device for an FPS)
So what happens is, instead of gunplay we get C4 chucking, laying in fetal position in a corner, RPG as primary vs infantry, M320HE ... Basically anything to avoid having to aim a rifle.
The controller players find other ways to "play the game" but, it's kind of bad for the skill level and quality of games?
I know a LOT of you are on controller so this topic will receive a lot of hate, but if you're honest, is the controller kind of screwing up the FPS genre in general? (look at aim assist and the perpetual drama around it for instance)
