Muting People
I've never muted anyone before because I didn't want to limit team communication. Last game I had a toxic jungler saying the craziest stuff like being 2/2/0 was feeding. He wouldn't shut up so eventually I muted him and my God, the game was SOOOOO much better because of it. I didn't realize how on tilt he was making me. We had been losing up until that point but as soon as I muted him we started winning team fights and I started playing a lot better.
I'm definitely going to make use of the mute button a lot more in the future. It makes the game bearable when you have a toxic player on your team. I know a lot of people are opposed to muting people and would prefer to argue with them but I implore you guys to try it out, its way better than arguing with someone who isn't going to listen to you anyway.
