Autofill has made my LoL experience far worse, and I want to talk about it.
There was a time, where I could be guaranteed my role as AP Shaco Top or AP Ezreal Mid (my current main), AND a team who was okay with it. That was Team Builder. Even if it meant an 11 minute queue time, if I wanted that role I could have it. If I wanted to make the personal sacrifice of my time to receive that role, I was capable of doing so, and without affecting the game quality or queue time of any other player. I loved the ability to play a role reliably over and over again. It was what lead to me falling in love with the champions I did, and becoming effective and skillful with them, so as to appease my team mates when I took it over to ranked.
But team builder was removed, and through some evolution Dynamic queue came to the stage. So I had to select two roles. This was not a huge hindrance, it simply meant I needed to be consistently good at a couple of champions, rather than just the one. So I did, I spent some time learning a jungler (Zac) as well as my main (Ezreal). This was not heavily impactful on my play style. I quickly accepted this new queue.
We now have a system in which two roles are not enough to be an adequate ranked player. I have recently been autofilled to support on more then one occasion, and the results have been bad games with unhappy teammates. Perhaps others are capable of managing three mains, but I myself am not. I simply don't play frequently enough for that to be a viable option for me.
I'm upset. I want to play what I want to play. I obviously have no entitlement to that, and I am thankful for the beautiful game Riot has created, but I don't understand this decision, and believe LoL is a better game with team builder.
