Better queue system?

I enjoy the new draft mode picking for your role in league i really do, I do feel like though maybe instead of having a secondary pick for the role you don't usually play why is it not possible to limit it to just your primarily role. Like for example i main i love her ever since i started playing in season 4 and i learned to adapt to different roles and champs...But with the new role choosing system its made it much easier to get jungle and destroy bronze 2 skrubs which i like trust me i do. Most people when they get their second role say "Oh i wasnt expecting this pick because i never get mid nor do i main a mid player". Instead of this whole 2 pick your role system how hard would it be to just say "Pick your first and best role and we riot will grab the next 4 teammates who arent looking for the same role you're in".
