URF idea for somewhat random URF

Hello everyone!

My Idea for URF is to give all 5 players 5 rerolls per game. With this idea, it reduces the pool to 25 champs (max) per team initially. In ARAM you earn reroll unlocks, however my idea is to allow players to earn a "pick" after 4 completed games. A player can use a pick to lock in whatever champ they want if they have earned it. If a player dodges a lobby, they lose their 5 rerolls next lobby. If a player goes afk in a game, they lose progress to earning a pick. What is everyones opinion on this idea? All feedback is welcome, please leave your comments below. If you like this idea, plz upvote!
