I posted on the Siege Reddit about how they could reduce XIM usage on console.
I said if they introduced native KB&M support on console with separate match making, and provided it with really compelling features that would be KB&M **exclusive** (exclusive being the key word here), e.g. zero aim acceleration, ability to lean from the hip, that would be incentive enough for people to stop mixing with controller users. You'd never be able to eliminate it altogether, but it would reduce it significantly. People would then say yeah Fortnite has native support but people still use a XIM...that's because they didn't offer incentives to move over to native. My idea would be about providing incentives.
I can tell you now if you gave me these two incentives (no aim acceleration and leaning from the hip) I would stop using XIM for Siege completely and only use it for COD etc. There could be SO many things you could do in regards to KB&M exclusive features, such as de-coupling crouch from prone, single button binds etc.
Anyway no one wanted to hear it. I got down voted to hell. No one is interested in practical solutions, they're all backed into their ideological corners and have taken an extremest "nothing but a 100% ban will suffice" attitude, even though I've explained to them so many times it's just not technically feasible to do without false positives.
IMO my solution is the only solution. But as I said people just won't hear it. I'm happy with my XIM, so...meh I don't give a crap anyway.
