QUESTION: Is Auto Fill bad for Ranked play?

I'd like to pose a question about the auto fill mechanic that's been put into the game. On the surface, it seems great. It allows players to try new roles, and increases the frequency of games played. However, I think there's a huge problem that's been overlooked, and that's the way some players (Iron/Bronze/Silver) react to being auto filed in the first place. Either 1- The player doesn't know how to play the role they filled into. 2- The player is a one-trick and decides Karthus Jung is a viable option 3- the player asks for a swap, gets denied, and decides to troll the entire team for sweet sweet revenge. Now, I know this probably only applies to a percentage of overall players in league, but seeing as this is a team game, it's very important that every player is at least on the same page as far as team comp, strategy, etc. And I just want to pose the question, "Is auto fill good for ranked play?" We've all been in a situation where the game becomes a 4v6 because someone on your team got auto filled and pitches a fit about it. As a support main myself, I don't typically get auto filled into a different spot (Support is the least picked role) But if I had a quarter for every time I've had to carry an auto filled ADC or deal with laning with a Darius one trick, I could afford to buy a switch and just play Smash bros. lol How would you guys feel if Riot removed auto fill just from ranked play? Personally, I would deal with fewer games and longer queue times if it meant having a more cohesive team experience once i'm actually in game. I'm no expert, just a player trying to climb the ranks. Thoughts?
