See I'm ok with "play my role or report" because that's a quick check in a chat log to see who the troll is. Just like it would be a quick check in a chat log for "switch or ban" but playing through a long game on a champ I wasn't intending to play feels more like punishment for wanting to report someone. Its one of those "But I get more satisfaction if I can actually click the button" type of things.
BTW I made this post right after this happened to me, and honestly I just dodged. I'll be that person when I'm using normals to learn a new champ. And honestly if someones first thought is to ban a team mate's champ in the hopes they just give up a role I don't really want to play a game with them.
