"Toxic" players actually love you.
Fuck this PC Culture. Stop being little bitches and take it like a man when you fuck up, you'll come out stronger in the end instead of hiding behind some Politically Correct curtain that mommy put up for you.. Someone is only being an asshole to you when you fuck up because deep down they want you to do better. It's like when you're 4 and you push a girl you like. You're doing it to get her attention.
If Riot were to completely turn off the punishment system for 1/2 a season and let players sort things out themselves, the natural chaos would inevitably turn into a place where the people that were "toxic" are actually more focused on helping the other players that are doing things completely wrong, instead, after the initial "Fuck you noob" these players are banned/chat restricted only to exacerbate the emotions and say "fuck the system".
The numbers Riot provides are complete bullshit. .002% of players are toxic or whatever that dumbass percent is. It's more like 20-35% of players are toxic, if not higher.
Built in voice comms would also help prevent toxicity and help teamplay. What the fuck year is this that a MMO doesn't have voice comms? Get with it you fucking noobs, Riot.
By the way, I love you.
