LP Freezing for players who AFK in Ranked Games

For the past 3 games in a row playing Ranked even with a break after the first 2 i have had an AFK after 3 minutes so i can't remake and i just thought to myself that not only should the rest of the team get a lost prevention because they AFK'd between 3-10 minutes into the game but they should be punished for wasting our time. So as a solution, If someone AFKs in Ranked not only do they lose LP but their LP freezes at its point until they win a certain amount of games without AFK'ing while losing still makes you lose LP.

So if a player AFK's and leaves 7 minutes in and we can't remake then they get punished for it immediately after the game.

AFK for 1 game = you need to win 1 game before you can gain any LP no matter how many times you lose, if they continue to leave or AFK while they still need to win a game or in quick succession then they have to win 2 or 3 instead of 1. If it gets out of control then they get suspended or banned from playing ranked or their account entirely.

To make this even better and to make it to where someone can't just ask a friend to carry them for their wins, until all their wins finished and they can gain LP again they can not queue up with anyone.

This is something I haven't seen done in any game I've played but i feel like this is the best way to handle it or be worked on and changed a little for it to be

(Note): I typed this pretty quickly because I had to leave soon so if things aren't properly explained i'll try to edit or comment more.
