Intentionally decreasing your team's chances of winning in a ranked game ...
by intentionally feeding/intentionally afk'ing/leaving/trolling should make you perma banned from ranked games at least.
It's that simple Riot ! It's that bloody simple !
Just don't let them play ranked games anymore !
What they do is irrational, illogic, dumb , selfish, egotistical and incredibly frustrating for the players who suffer due to it.
Why ban those players for a day, or a week, or bla bla ? Just perma ban them from ranked on their first offense.
And make it so if they actually send a valid ticket to support with a rational explanation of what they did or an apology, they get unbanned. But only for the first time they got banned, and tell them that if they do that again they won't be playing ranked anymore FOREVER. If they are not able to make a nice rational explanation of why they did what they did, don't unban them, they don't deserve it .
I'm tired of losing 1 in 5 games due to some selfish dude that thinks the game is all about him , and if someone doesn't do it his way, he will ruin it without us being able to do anything about it.
Your report system also sucks major balls. That's why people are so god damn annoyed and angry while playing this game. We feel like reporting that dude who basically shat on 40 minutes of your time isn't going to do nothing due to us not knowing if he got punished or not.
