Forced Auto-Fill in high elo promotes toxicity

If someone is autofilled into their worst role they are just going to be flamed by their entire team. Just experienced this in my last game where I was auto-filled into support and I had to deal with being trash talked by a 12 year old ADC for 25 minutes. I made the mistake of saying I was auto-filled so the whole team saw me as the target to blame the loss on. Yea I did bad,, but so did the 2-8-3 top laner, that got his role, the 6-10-1 mid laner, that got his role, the 2-7-3 jungler, that got his role, and of course the 5-8-4 ADC that GOT HIS ROLE.

What was the point of auto fill? It didn't cut down the queue time, I still spent 12 minutes in queue, all it did was make it so I had to play in a game that I wasn't going to be able to carry while I was scapegoated by those that did get their roles and failed horribly with it.
