Well today I found out that the ban system is still working nicely.
I had a game earlier today where a on my team Singed lost his lane, flamed Lee Sin for not ganking his lane, and proceeded to throw the game by not helping 1 little bit unless he happened to be standing in the middle of the fight when it broke out. When everybody else on the team told him to stop flaming and start playing, he muted everybody and continued to flame. this guy tried to steal buffs from our Orianna and Caitlyn and would run off in the middle of teamfights to go farm top lane (that is when he even bothered to show up). At the end of he game he said that he was trying to throw the game because we were toxic to him (nope) and we deserved the loss. I got up to go to the bathroom and when I came back me and 2 other guys who played with me last game (Ori and Caitlyn) all received the message that Singed had been punished.
Hell fucking yeah. Feels good to get that message.
