Why this new role select is broken.

In the team builder game mode, queue times would be so long if you were searching for supp or some other role no one played, but this is ranked, my main is jg and when i get my secondary role MORE then my main this is broken. ranked is the MOST played mode, even if you gave us the role we wanted and didn't search for others who main that role as well queue times would still be significantly low. SO WHY NOT FUCKING DO IT YA TWATS.
