isn't immune from cheaters. And it's not only an issue on PC, where cheaters use tools like aimbots. Some folks use XIM devices so they can play with a keyboard and mouse on consoles. This is against Blizzard's rules, as KBM players typically have an aim advantage over those who use a controller, even though the console versions of the game have features like aim assist.
Starting in Season 11, which should get underway in June, the developers will tackle the issue at a broader level. The first time a console player is detected using an unapproved device on consoles, they'll be banned from Competitive modes for a week. If they keep using KBM or other unapproved peripherals in casual modes, they'll get a season-long Competitive suspension, only have the option of playing with other KBM users in Quick Play and lose access to aim assist features.
There are accessibility concerns here, though, as some folks simply can't play games with a standard controller. Blizzard says that it has done its "utmost to ensure that players with accessibility needs will be less likely to trigger our detection." The developers say they will tailor their enforcement actions so that folks with accessibility needs can still land a sick Earthshatter or keep healing their teammates.
With all that said, Blizzard is looking into adding official KBM support on consoles so folks can play the game that way without negatively impacting controller players. As things stand, console and PC players are separated into separate pools for Competitive play. So to make things fair, Blizzard would need to shuffle console players who want to use a keyboard and mouse into games with other KBM players and no aim assist.fair and more enjoyable for the majority of players.
