Never getting mid as a mid primary?

So I guess I posted this in the wrong section last time, 15 games I've queue'd for mid primary and have gotten it a single time. Why even allow people to pick primary roles if you're going to get it less that 7.5% of the time.. I understand that me not being good in other roles is a problem but it's absurd that I can't even play the role I enjoy the most even 20% of the time. I get Riot loves the idea of being able to get into games quickly but it's absolutely worthless if the player's queue'ing for mid get a role they don't enjoy and end up suffering through a 30 minute defeat. Fix this bullshit, give me longer queues, let me and others mid.

Holy shit game 16 -http://i.imgur.com/4CzBy2V.jpg its a miracle
