Dynamic Queue rarely giving primary role is an issue for me

For mid lane mains it is awful how little I get mid. I could understand getting mid maybe 40-60% of my games, but I'd say I am getting mid once every 5 games at best. so around 20% of the time i get my primary role. why even have primary secondary if its not weighted to give you primary more often. if mid is that popular than there has to be some way of addressing that. is anyone working on this? right now im just frustrated I am always stuck with secondary role regardless of what I pick.
