Used to get mid more often by saying "Mid pref" in draft pick

I literally used to get mid far more often in the old draft pick than now. I was excited for this season to start practicing new mid champs like Ahri and TF and try to climb to diamond. How can I even practice these champs ever if I only get mid like 30% of the time at best, and when I do get it I need to pick my main so I can actually win and make up for all my losses playing other roles?

I just don't find other roles as fun as Mid so sue me. Still hoping we'll be able to queue for only one role soon.
