There should be a 3rd option in ranked if Autofill stays.
The whole concept of Autofill defeats the purpose of the primary and secondary roles and negatively impacts ranked play. I would rather wait a little longer in order to play a position we play best at to increase our chances at winning. If the Autofill system stays then there must be a 3rd option along with Primary and Secondary roles. That 3rd option should be "Least preferred" and as the name implies, it would serves as a way to avoid playing in your worst role if Autofill is activated.
The last thing I want is to lose a ranked game because I or someone else was forced into a role that we're not good at. Normals is fine and understandable as its a place to practice and experiment but ranked is where you bring your best to the table. You dont force a wide receiver to be your defensive linemen in a football game.
