Teambuilder Match Up Suggestion

Hello fellow Summoners and Rioters...

...I think we all know this situation. You want to practice with a new champion and because normal blind picks doesn't ensure you to get your pick and lane, without things getting salty, Riot fortunatley, invented Teambuilder. But in Teambuilder you often have to wait long because there're too many unpatient people out there...people often join and leave again in a matter of seconds instead of waiting...

So, my suggestion is...

...a system that allows you, as the captain, to invite players that are currently searching for a teambuilder slot...of course without showing tier and so on...
