I'm surprised at these answers. You can mute chat, but cheating actively ruins your progress in game. I'll take a toxic team that I can ignore if needed over getting swept by a cheater.
Yes lack of communication can lead to a shit game but even with the best communication, you can't prevent cheating.
How do you fix people getting so mad at you that they figure out who you are in real life, and send a SWAT team to your door, saying you're a terrorist or some nonsense?
Muting isn't some magical cure all.
Or to out it another way: ruining progress in a game sucks, yes. You know what sucks more than that though?
Dying, because someone got that angry at at online game.
Which is rare, but nonetheless happens, and even once is too much. Toxicity is not some online-only problem, they cross boundaries all the time.
Cheating very rarely rises to levels like that. Whereas, swatting, yes, that's also uncommon, but it's also something I don't personally have to deal with to get his terrible it is and how it should happen to no one, even if it never happens to me.
They're just completely different world due to stuff like that. Don't have to have it happen to me personally to nonetheless wish the world was better for everyone else, to wish no one would have to endure that all the same.
That's why it's so hard for me to understand people picking cheating. Because even if it doesn't happen to me personally, toxicity nonetheless affects people's lives in ways cheating never will.
So that being the case, if I had the power to pick one or the other, of course I'd pick toxicity. Can't imagine doing otherwise and treating cheating as a higher priority anyway, when I could not just be improving lives but flat out saving them by picking toxicity instead.
