Hello Autofill my old friend...
I don't think Autofill is intended as it was supposed to be.. I am currently in a 5 queue dodge streak today(Trying to get into one single game). I understand that it's supposed to make que times shorter, but it is taking just as long with autofill as it would without, people dodge because they don't want to play support or another filled roll. People want to play their respective roles even if que times take longer, I can understand if its higher elo (Diamond3-above) but autofilling bronze people isn't necessary.
-Edit I am on a 10 dodge streak now. 8)
