Stop Complaining About Autofill
It's like you a) weren't here before season 6 or b) forgot what it was like before season 6. You had to go into every ranked game preparing to play any of the 5 roles. There was endless conflict in champ select over who on your team would get which role. Most of the time both teams had players playing off roles.
Even if you get autofilled as much as the system allows (let's conservatively say 1/4 games, and we all know you don't get autofilled this often), guess what you get the role you want 3/4 times. This also ignores the fact that you're autofill protected in your promos.
Seriously as far as ranked games go champ select is the best it's ever been, enjoy it.
