Autofill system in normal games sucks!

What is wrong with normal games autofill system? Is it ever getting fixed? I pick mid as my primary and jungle as secondary role but out of 10 games I get around 7 jungle games and rest mid. Queue times aren't even that long (cca 1 minute). I feel like you should only get autofilled if queues go more then two minutes. Can you please increase the queue times but make it so players can get main role more consistently, or add option which player can choose if they are down to wait more but get their main role more consistently (ofc increase queue times for players who choose that). Also a lot of other players also report that its hard to get mid often in normals.
