The only thing wrong with crossplay is that it appears that many xbox players are using no recoil and enhanced aim assist. Not sure how, but I have seem it a lot.
Oh really?

And I met a guy at a tech conference who told me there are other ways on an xbox. I've seen the funny business WAY more often from xbox players.
Point is, crossplay is ok, but cheaters ruin the game and make it not worth playing sometimes.
