I, along with others, would love to see a matchmaking queue for this. Stopping the dodges would be a huge + to one of the funnest game modes in league right now (imo). Also I think it would be nice to have an aBam and aDam selections if this is implemented as it would get people started in the aram scene. Those people that say 'O I don't like the idea of random 5v5's' would play some adams or abams and realize how fun the map and game mode itself actually is, and how its a lot easier to just enjoy the game even if you get a teammate that is just super bad. Then they would try all random and start to enjoy the chaos that is aram.
Another issue that this would help with (although not as much of an issue as dodges) would be that a matchmaking mode would stop the occasions when you join a 3or4or5/10 aram game that ends up taking a couple minutes to fill up only to find that the host is afk.
