idea for new team builder (that isn't just making it pick one role)

so I keep seeing everyone making the argument that they want to pick one role. but Riot and many others are explaining. If we allow picking one role only, queue times will be HEAVILY affected

so what can we do? everyone has games where they want a specific role :/ but we also don't want to kill queue times

well why not do something similar to the reroll system in aram

every 5 or 6 games you play you earn a "token" that guarantees you your primary role for one game. those that don't want to use it can choose not to.. but it would mean for those that REALLY want to play their main role for a game can do so.

by giving tokens through playing games, it also promotes playing MORE games, which might further improve queue times.

I think this is just one possible solution for this problem, and I'd love to hear thoughts on what people think or other ideas on how to solve this problem

but just allowing one role queue is not acceptable and that's obvious, I think this idea might be a step in the right direction... thoughts?

tl;dr use a system like aram reroll that let's you get your main roll if you play enough games
