Players stealing roles in draft
Recently I have had a notable uptick in players attempting to or actually stealing roles in draft, both ranked and unranked. Players get onto the draft screen, see they are first/second pick, and immediately declare "role x" regardless of what they actually are. If the team flames them they usually back off, but if they lock in their pick either the player who just lost his intended role is screwed or the team is. Is their a way to punish this behavior other than reporting them after the game? It feels really bad when a player gets forced into a role they aren't good at or weren't intending to play, and it hurts the team overall.
P.S. I realize that this is similar to getting autofilled to a role you don't like, but in that case it is just a necessary evil of the system, not players actively screwing with other players.
