With toxicity being such an issue in League
Why hasn't Riot put in a communication system similar to Rainbow Six Siege? I've been playing it recently and their is very little toxicity. Why? Because most communication is done through voice and being even remotely toxic gets you instant banned. While it will be ineffective to instant ban people right in the middle of the match for league they can just be banned right after the match. And since most communication is done through voice, most people are too afraid to actually be toxic to others.
