I'm Starting to Hate Dynamic Queue - Bring Back TB or Let Us Choose Only One Role

Please. All I want is to practice some mid laners since I have yet to decide who I want to main right now. Ideally I would take support as secondary but that leaves no chance of getting mid. With ADC as secondary, since those are the three roles I enjoy, I get mid < 10% of the time. One in 10 games is not good practice.
