I'll tell you in my opinion, PC and those who play on the controller, because there's a people who play on cell phones that don't even have a kit, as you want certain players to have a "good experience" playing on a server, which you can barely play on along with others, I would recommend splitting between pc, controller and mobile players, because I think it would be fairer that way, to put everyone together What is the chance of a person who plays on cell phone defeating a pc?, 10% ? or less, because we know that some platforms have more advantages than others, I just don't think it's fair to bring them all together
