How to ALWAYS get your preferred role in the new Champ Select

I was looking up when the new client launches (as i thought it did today) and found out it launches tomorrow. While i was there i decided to read the comments and noticed an overwhelming majority of the people are upset team builder is gone because they aren't garen-teed the role they want, instead they get a 50/50. This isn't necessarily true, there is a way to ALWAYS get the role you want.

Requirements: Que up with at least 1 friend

Choose your primary role, and have your duo choose theirs. Select each other's primary roles as your secondary roles. Using this method you will always get your preferred role, and if you don't you can swap with your pre-made to get it anyways. For example you want to play top and your duo wants to play jungle. Select top for primary role and jungle for secondary and have them select jungle for primary and top for secondary. The match is found and you got top, good! Or, the match is found and you got jungle, ask you friend to trade with you and you got top, good!

To clarify: i am not on PBE, i haven't tested this theory. I just assume it works, why wouldn't it?

EDIT: idea posted above won't work. Keeping thread up so others can with the same idea can see the results. Thanks to shaowsaotome for the info straight from pbe! On the bright side supports and junglers may be getting more popular soon

Requiring two positions ensures short queue times and that no one on your team gets stuck in a position they don't want to play. We know some options (cough support and jungle) aren't always quite as popular, and plan to incentivize these roles with IP bonuses if necessary.
