This may be a touchy topic as a lot of console gamers out there right now will jump to arms at even the mention of mouse and keyboard or m/k for short (just because ill be saying it a lot in this post) because they feel it gives pc players an unfair advantage over console players.
While i dont entirely dissagree with that statement, as when using a m/k in combat it allows for faster turning, weapon switching, more stable movements, etc. BUT instead of saying that pc players should be punished or locked off on their own servers for having a pc be their system of choice, why not just add m/k support to the xbox version?
It would level the playing field because that way, anyone who is concerned with the advantage pc players have could just go to the nearest electronics store, drop $20 or maybe even less and get a decent m/k combo.
When i plugged in my old m/k into my xbox i noticed some functionality was there already, like being able to switch weapons, access my inventory wheels, walk (only while holding shift), but no response from my mouse. So clearly somethings already there, why not just copy the m/k functionality and keybindings directly from pc to the xbox version and call it good and even? (I know theres more work than that, but at its simplist that would be whats being accomplished) idk, just a random 4 in the morning thought. Though this is something i personally would LOVE to see happen.
