Riot tried no auto fill.
What happened was considered bad enough on their end that they felt required to put autofill in.
Let that skin in for a minute. Riot felt it at least more beneficial if not necessary to sometimes have players on their undesired positions over waiting likely 5+ minutes for a game.
Was it that people didn't want to wait? That the number of games were going down drastically? Were lots of people quitting the game (or just ranked) because of it?
I do not know, but riot would not have put autofill into place if there was no beneficial reason to do so on their end. And the fact that it has been kept for several years with no real talk of it being removed suggest it is not going anywhere.
So with this I conclude you are wasting your breath requesting for autofill to get removed. IF anything were to change it would likely be a modified version of first pick which was in place until season 6 happened and allowed for players wh oare willing to communicate the menas of giving themselves the best chance of victory based on what players in the team could do.
Perhaps trading pick order instead of champs might be a beneficial change since we now each get a ban meaning the first pick advantage of 3 bans is gone and that is about it.
