Champion select on normal games

One thing that has been annoying me recently is the champion select on Normal games. It is an unfair system as it is who types the quickest to get a certain role. This means, that 90% of the time i am left with adc or support. They can be fun roles, but feel like I have overplayed them. I would like it if RIOT made a fairer choosing system which either you only have one role, or get your first role 90% of the time. I personally wouldn't mind waiting an extra minute to have a fun game. I also can't dodge the queue otherwise I will have to wait 5 minutes and it would eventually stack up. If anyone else has these problems please comment to raise awareness and voice your opinion.
