Remove Autofill
In recent matches, I've seen the number of dodges go up by an absurd amount. This is caused due to people's picks "not mattering" as they get stuck with a lane they don't want or are unable to perform well in. This in turn causes the queue times to be much longer than if autofill was not present at all. For example, earlier today I was in a lobby 6 separate times, in which someone would dodge after all the champs were locked in. On the seventh match I ended up support, and as always when I get that lane... miraculously no one dodges. I'll play the match, but I won't enjoy it at that point. I perform better in every other lane than support. So my suggestion is that instead of having autofill be present, either remove it entirely, or take things back to how they used to be. At least teams communicated prior to champ selection then. People would talk about lane preference and strategy, and then would all get what they wanted. With this assigned system, the lobbies are usually quiet, minus the people complaining about the autofill system.
Old System = 98% of the time you get the lane you want New System = 56% of the time you get the lane you want
I'd prefer waiting 10-20 minutes longer in a single queue than deal with 20-30 minutes of queue dodges and having to re-accept repeatedly to find a match in which you get shafted anyways. Furthermore in ranked, the goal is to play what you are able to perform the best with to help the team get to victory. In this case, if the system won't be removed from normals, at least have it removed from Ranked. There are plenty of players committed to ranked play, and the wait times won't suffer.
