I'd honestly rather play with potty-mouths that actually try.
Than the people who do things mechanically to literally ruin the game. You can mute an annoying toxic who keeps complaining, you can't do anything against someone who intentionally ruins your games because they want to be selfish.
Game a few days ago. Mid feeds 0/7/0. Freaks out and says the whole GG thing, surrenders. We tell him no, other lanes are ahead and we're fine, we've even won two team fights. "Yeah but I keep dying in them and am not doing anything im useless and not having fun just surrender and let me go to another game." After refusing to surrender he decides to tell us "Well if you're not gonna let me leave I'm just gonna feed them more so we lose faster so I can get this over with." ** Which he follows through with. Fast forward to today, he's still playing. ** _Go to yesterday: _ Our top says he has some lag, we tell him just play safe then and try not to engage too much. "Nah, I can't play like this have fun guys." AFK's before level 2, he's the only tank on our team, and it tilts our JG who now has to take over top with a machete, we get stomped. EVERYONE on our team and enemy team says they're going to report him because the game was such a boring steamroll. **Again, dude is still playing. **
The only way I can view this kind of behavior/punishment system is the kid in class says a curse word so he gets a weeks worth of detention. The bully beating the **** out of kids in between periods goes un-punished, because a teacher doesn't actually see it happen and are too lazy to investigate.
I'd rather be in a class with a kid who's annoying than be afraid to go outside of class because I'm afraid of the bully who's going to beat the **** out of me.
