Auto Fill Activated

Why are we picking roles if 1/2 the time we don't even get the roles that are posted. Plus for whatever reason if someone dodges then you could possibly lose your role autofilling in diamond+ makes sense because their queue times can become over 30 mins but i would rather wait 3minutes for my queue than get support. Literally just had 3 game dodges into support. My least knowledgeable role. There is no point in having us pick roles if you're just going to autofill us to lose a 1minute on the queue times. It's ass backwards....
