Will Battlefield 2042 be playable with a mouse and keyboard on Box series S

@Blackidus That is very incorrect. Battlefield is a competitive game and has numerous esports leagues setup around the world. And has been since the days of BF3. People also play  siege for fun, but the point is as simple as I made it. If you are using a piece of equipment that is not permitted by the game, that gives you an unfair advantage performance wise. Then its cheating. This applies to many games across console and as said most of them take it very seriously and even permanently ban people caught using M&K in any games regardless if it is in a competitive setting or not.

Yes doing selective matchmaking is a solution but it then creates another problem of people not being able to find games. This is apparent in CoD and apex legends. It takes on average 5x longer to find a game once you have disabled crossplay then when you have it enabled. Not because there are more pc players than console, but purely because everyone knows how much longer it takes so people do not bother. Pairing console keyboard and mouse players only with pc players again is a good idea, but whether it can be implemented is another story im not sure if you can create a code/mechanic that would detect this and how complex it would be to create e.t.c. You would essentially have to create another layer to the matchmaking system that detects the type of input being used by the player. This relies on whether the console actually shares that data which I do not know if it does.

Your 3rd point is literally a straw man argument. Devices such as monitors, headsets are personal preference and has nothing to do with the control input method. If you are playing PC and it is a low-end vs high-end then you clearly did not look into things enough when your brought your PC or got into PC gaming. We are talking exclusively about control input methods here and how it creates a huge disadvantage.
