This is getting out of hand. Players literally are bragging about being MnK on console. Some show it off in kill cams. Some even include it in their gamertags. I have a tech background. I understand without help from Xbox or PlayStation it is really hard to to fix MnK on console. That said you can very easily discourage it. This is not a perfect example but it should get the point across. ALL MnK players have their sensitivity set on max. Have gadgets in game that produce greater penalties for higher sensitivity. Elas, Echos, etc. Introduce a new secondary item similar to the flash bang but call it a stun grenade for defense. It should be simple to develop. The stun grenade could pull aim in a random direction. The higher the sensitivity the stronger the pull and longer the duration. Please. Do something. I love this game but I won't spend another dime on till this is fixed.
You could also do a shadow ban thing where each player is assigned a probability of being MnK based on stats like headshot percentage or key input patterns. Then only match players with similar probability ratings. Or just simply match high sensitivity players with other high sensitivity players.
