Riot: Your really need to impliment a behavior system for trolls during picks.
I know that other people also have this problem as well. But when I get top and have my champion banned because some jerk didn't accept no for an answer when I got top and did not want to swap in draft pick.
Seriously I don't know how many times people have to say this, but it's one of the few way someone can get away pissing on other.
