Autofill brings the worst of both worlds
So, now we have autofill, which makes matchmaking more like it was before dynamic q started, when we could solo q. Now, who do you think is going to end up getting "autofilled" to a random role? That's right, the solo players, because I'm sure it prioritizes roles for premades. So, not only do I have to play with/against a premade, I might have to also take a role I'm not good at or haven't played since dynamic q started? Give me a break.
Congrats, Riot, you've just combined the worst features of both queue systems.
