My biggest concern is the growing wave of users on console who are playing with mouse and keyboard. If they don't find a solution to peripheral-rigging, the input-based crossplay will be rendered useless. There is enough XIM cheaters as it is and games like Rainbow Six Siege have been ruined for it. I ran into a handful during the alpha and it was always going to be an issue without crossplay but running into players like this makes the experience unfair and unplayable.
