To be honest this concept of ''Autofill'' ruins the ranked system and won't let people play with their full potentional, especially in your placements. I just got support while i don't main it as good as the other roles (In soloQ. With Duoq I don't mind going support because we practiced for synergy), however in Soloq i just get bashed and flamed. Who the fuck cares if you have to wait abit longer for a matchmaking while autofill just reduces your overall winrate and places you in a shit division.
I was Diamond 3 in season 6 so i wonder which division i get with this shitty permanent autofill :^)
