I've been trying to get into a game for almost 45 minutes now. Auto-fill needs to be made optional.
After seven dodged lobbies, I finally got into a game with a 4-man premade. They wanted Kai'sa, but the enemy team first picked her, so one of them left as soon as the game started to allow a remake, and switched accounts.
Three dodged lobbies later, I finally get into the next, and I'm auto-filled to support. Which I don't want to play in a normal. So I dodge, and now I'm waiting 5 more minutes until I can queue up again, 45 minutes after I sat down and decided 'I want to practice my Cassiopeia.'
This system has zero value. Forcing it in normals provides absolutely no benefit; anyone who doesn't want to play an auto-filled role (ergo would opt out of it if possible) will just dodge at the end of the lobby, wasting everyone's time.
