Wait... so the person you want banned wanted to play Kat mid, and you questioned and trash talked him because you thought they were gonna pick a counter. Then he said he was gonna troll. First off I doubt he was gonna intentionally feed. 90% of the people that do that say it because they want someone to dodge. Second off, you trash talked him first. If he wanted to play kat mid don't question. I'm sorry if you don't understand that picking a champion before the enemy team allows them to pick a counter and strategize. That's the point of having people pick for you for something contested or something you don't want them to counterpick. You obviously don't understand the way Draft Pick works, and you need to learn how to cooperate with a team.
