I have no proof
There is no way to prove that the person playing Talon queued for jungle, originally had Rammus, asked me who I intended to play mid (I had last pick) so I highlighted Talon. He then picks Talon and says, "I'm going to feed mid." Changed his
to
, was verbally abusive in champion select chat.
When game starts, he immediately runs into mid tower, takes 3 tower shots then runs into enemy jungle. The entire time during in-game chat, he's the nicest most positive guy ever. "We can still win." "Don't give up guys, we got this." "Stay positive, game isn't over yet." "We're late game champs, we'll make a comeback." etc etc
The other 3 teammates flamed him and they'll probably be banned since he said he was going to report them. I've learned my lesson from flaming players like this because that's how I got permabanned. But this guy, this guy will see 0 consequences for his actions just because he didn't say anything bad during in-game chat. Pre-game and post-game chat toxic, in-game chat he's a perfect example of what a summoner should be.
When my 1st account got banned due to flaming people like this, I got all negative feedback from the boards. Now here I am, reformed, not flaming, account in perfect standing (I get all my loot, honored most matches, PBE access, gifted for attitude and play, etc) asking... WHY HASN'T RIOT IMPLEMENTED A WAY TO DEAL WITH THIS SHIT YET!?
