It happend to me many times, that i got assigned some role (I'm playing mostly mid and jg), but some other player, who was assigned e.g. support and picked before me, just said that he would play my role instead and picked a champion for that role, even though i didn't agree with it. Regardless of them feeding or not afterwards, this does not seem like a sportsmanlike and fair behaviour to me and i think there should be some form of punishment for these people. Unfortunately, there is no such mechanism in the current version of the game. I would suggest that there is some report possibility just for this case. What is your oppinion on this?
