Toxic people are the only people who mute others
It's a joke, at this point. If you're toxic, and you start shit-talking your team, they're not gonna mute you. They're gonna shit-talk back, and you both will just keep going until the other person says one of the Instant Feedback System's trigger words. Because that's how to properly troll in League --- get someone angry enough to start flaming. Amazing.
But there's another breed of toxicity. It's the kind of people who just mute everyone at the beginning of every game. In RANKED. Just a while ago, I was begging my idiot team to come help me at Dragon, since their team was dead, and I was too low to solo it. No one comes. The only person who tried to help was my ADC, because she and I were the only people with Gold borders in the loading screen. Our Annie just sat mid and watched. Even the enemy mid laner came, and she just stayed mid and watched. We spam pinged her, we shouted "ANNIE WE NEED YOU" in the chat, yet she didn't respond to anything. She cost us the game, just because she abused your frivolous Muting system. At the end of the game, we're all asking her why she was trolling so hard, and she respond with, "Me? Oh, I'm sorry! I muted you all at the start of the game!!!"
Man, I really hate Silver.
