Like the title, just get rid of this system already, queuing for the sake of queuing while dropping the quality of the game is the worst idea ever.
Everyone expects to play X position. I don't queue support to play mid, I'D RATHER NOT PLAY IF THAT HAPPEN.
After all this time I don't get why Riot doesn't want to adopt a logical system. No, not every part of your game is enjoyable for everyone.
Edit : Also, let support pick the supp lane only.
