There’s no need of even make pc players use a Controller, they could easily just set an option to enable and disable Crossplay. It’s on console, dunno why they totally disabled the option on pc it makes no sense at all. Wanna play with your buddies on PC? Well you accept to have a partial disadvantage (Dunno if Aim-Assist is good in the console version) but hey, they got ya covered. In extremis you can always ask as a Console player the right to have M/K support added.
