Auto-fill has reduced ranked games to a dice roll. When is this going to be improved?

Nearly 100% of my ranked losses right now are caused by auto-fill, and I assume the vast majority of my wins are also attributed to auto-fill, because a player in a role they absolutely cannot play essentially turns the game into a 4v5; in most cases, the team with the auto-filled player would be better off if they just left or went AFK.

I'm estimating that every single game right now has at least one auto-fill, and it's not always support. I'm encountering auto-filled jungle and top significantly more often than support. I've even encountered a couple of auto-filled mid lanes, which leads me to believe that the entire feature is broken or too aggressive in trying to start games quickly, with no regard for whether the match-up is good.

Yesterday, I had a 5 loss streak, where every single loss had at least one (often two) players on my team auto-filled. In most of these games, myself and another player both won our lanes and helped the auto-filled players stay in the game, but we could not compensate for their lack of knowledge and skill with their role/champion. Even giving them a gold advantage, they couldn't really do anything, because they couldn't effectively play their champions.

This may be fine in normal, but it's not okay in ranked. Something really needs to be done; ranked games should always prioritize a good match up over a fast queue.

Also note that auto-fill is not equivalent to the pre-draft issue of having to play all roles. In those days, you had to play most roles regularly, so you were always in practice and proficient at all or most roles. Right now, you play your primary role in 90% of games, which leaves you out of practice with the other roles.
