Game Mode Idea: One-Trick

Sort of like the old team builder this would be set in an singular lane for solo (top/mid) with their components. Duos can go botlane to practice 2v2. Essentially, you queue up the champion you want to play then you look at other people's queues and choose which one you want to practice 1v1. They have to agree with your choice which then puts you into a lobby. I suppose the games would last 7-10minutes which would emulate the laning phase.
