Main role

I am really curious about your past 20 games. I wanna know how many of them you got your main role. I got half, which is 10/20, it's like rito knows when you're not good on other roles and puts you there on purpose. Every single time, absolutely every single time when someone leaves champ select where I had my role, I either get the second one, or most cases autofilled to support, which I am terrible at. I also notices that there are times when even if you're autofilled protected it still puts you autofill....I mean wtf... and also, one game after autofill protected ended and its activated, boooom autofilled. I mean I don't know what to say anymore... What do you think of this?
