selecting roles: how to fix the chances of getting what you want (yes rito, i want you to read this)

So, we don't have this pickmode in euw (yet), but i see a lot of people raging because of getting their secondary choise, and i think there's a way to fix this.

Riot, if you would make sure that out of the 10 selected roles (5 people, 2 roles each), every role occurs twice (so 2 adc's, 2 mids, 2 tops, 2 junglers, 2 supports)

This would effectively make the chance of getting your primary pick 50%, 'cause as it stands right now i've got the feeling that it's perfectly possible to be matched as 5 people who prefer mid with each one a different secondary role (thus giving you only 20% chance to get what you really want)

I don't think it would increase queue times by a lot either, as all different combinations would be seen!

Opinions?
