A Somewhat Annoying Problem With Auto-Fill

Let's say you get the notification of, "You're possibly going to get a different role than one you queue for".

Now, I get that this is for queue times but- I still said I wanted Support as a primary. I didn't get it. Literally the one role everyone needs in a game, to the point of it being detrimental to the queue times, and I couldn't get it because of auto-fill.

This seems just slightly counterproductive. Can we at least nullify this so that if you set your primary as Support, you GET Support? I'm aware it's probably rare that someone intentionally WANTS Support but this is the system literally working against itself. I could've been used in any of the thousands of games where a Support was needed- but instead I was relocated to another one where it's almost a sure thing that someone else was thrown into Support by the same system.
