If i Want to get in a queue in a reasonable ammount of time i have to go support.

I would greatly appreciate it if you guys at riot, initiated some sort of system that allows for those who frequently go fill and support to have shorter queue times for different positions. For example, if i queue for support 5 games in a row, then the next game i play where i choose some role other than support, i should get some priority. I only ask this because i feel as if at least at lower levels, significantly less players want to support than anything else, and so, if i want to go anything other than support i have queue times between 5 and 10 min, then usually i get secondary anyways. I think there should be some sort of incentive to play support some, maybe this not be the case in a ranked setting but at least in normals and such. Thanks!
