Didn't actually understand anything you said here, but you said ranked teambuilder.
Now hold on bud.
Dynamic queue is anything but a ranked teambuilder.
Teambuilder is where you pick the exact role you want, choose your summoners, runes masteries, and you go into a queue, and a player can accept you onto his or her team, or you can make a team with friends or alone, accepting other players.
Dynamic queue is where you choose a primary and secondary role, and you most likely get your primary, unless you put fill or support secondary, and you can queue with 1-5 people in ranked, people are mad about that part, queueing with 5 people.
Learn the facts before you make a post like this, and make sure people can read what it is you are even talking about.
Have a nice day :)
