This would be amazing if they forced it. Scorpio with mandatory mouse and keyboard support. Crossplay can suck it. I don't want to play with pc users.
Why, because you don't want to get mixed in with arse hats that resort to using hacks? Then just stick to private lobbies when you do cross-play. It's not hard to set them up, and all you need to do is stick with people you know without a doubt are not playing with any kind of hacks to give them a ridiculously unfair advantage.
In the event that you do come across a random in pubs that you believe is using hacks (and have evidence to back it) then just report them, spread the word to everyone you know... though it doesn't matter where you go, you're always likely to run into people that get a kick out of being total dicks and just want to ruin other people's day.
Saying that I can't/shouldn't play the same game on my PC with friends who're on a different platform because some people don't like PC's for whatever reason, is like saying I can't/shouldn't make calls or txt from my Android phone to anyone that has (for example) an iPhone because some people don't like Android. Do you see how dumb that sounds?
