My problem with the queue system

The one thing that has kept me coming back to league since S3 is playing my favorite champion, Zac. I used to main him in ranked and play jung zac in 80% of my games and it was always fun. With the new queue system I can never get my primary role of jung in order to play Zac. I queue up as primary jung secondary supp and of the last 15 ranked games played, i got jg twice. I understand that less people queue in as supp so it is easier to find matches but there should still be some sort of balancing system so i can get my primary more often. I really don't mind spending a little more time in queue in order to play a game that i will actually enjoy. Of course people keep telling me to make my secondary mid or something so that i can get jung more often. However i feel that defeats the purpose of the queue system. I play secondary support as that's what i'm good at and if i were to get mid or adc I would end up having to dodge of feed. Without playing my favorite champ/role the game just gets boring and it really has been making me want to stop playing lately. I really just feel like the primary/secondary role choices need to really reflect their names better that's all.
