Chat restriction
Chat restriction doesn't help with toxicity. It's negative reinforcement, and it ruins games. Another solution is needed.
I was playing Zed, and Mundo flashed in front of jinx - right on top of her - and on top of having not done great this game, I accidentally ulted mundo.
Can you guess what happens next? My team starts cursing at me.
I can't do anything because I'm muted for three minutes. Oh yeah, on top of getting camped the shit out of, getting 2 counterganks, and getting focused, I'm now getting yelled at.
Every 1 minute you get a message and start with 0. It's the best solution of the same style.
