Suggestion: New way to implement "Team Builder" for Ranked

One of the biggest issues with League in general (and ranked in specific) is that it's supposed to be a TEAM game and yet you're (most likely) constantly playing with "randos". So what if there was a new way to Queue that worked thusly:

1. Click "Ranked Team Builder"
2. Choose your roles as per current
3. Game goes as normal
4. Once game ends, if you played your PRIMARY (or if queue'd as fill) you're given the option to stay in your current role (or leave the team) 4b. If you played as your secondary or "autofill" you can offer to switch roles with another player, if they accept next game plays with your new role considered your "primary" (considered secondary/autofill for the person swapped) or you can just keep your role or you can leave
5. You can vote to "kick" a player. If 3+ players choose to kick one, that player is booted. If less than 3 players agree then any players who voted to kick auto-leave
6. Once roles/departures are settled, the team queues and fills any missing roles

Ideally, after a small number of games, you SHOULD be able to find a solid TEAM that can work together. At worst, you should be able to slowly build up a group of people that you mesh well with. And ideally, you should only need to replace 1-2 people as time goes on. It should also be easier to identify trolls/toxic players since they will continuously be kicked. It should also cut down on "elo hell" because most people should have a "known good" (or at least "decent") set after a small number of games.
