Alright, I thought of something that would really improve competitive queue. So you join a game and you encounter one of those people that just aren't there to win. They are there because to them "overwatch is just a casual shooter and nothing matters and comp queue is just better than QP or Arcade".
What if Blizzard just added an option where you could just delete this persons account. You could just go onto their computer and just uninstall the game right there and it would restart the match with all 12 players being normal competitive players who want to win whatever that takes.
