afk protection for ranked

while i know beyond shadow of a doubt there is several other threads complaining about the lack of afk protection in the game i have just one suggestion. if there is a "player" or lack there of who is under level 6 at the end of a game, lock all players in their current tier except the afk individual, and have them suffer double LP loss. i have for the 4th time lost progress that i cannot get back in a single game as it takes a minimum of one game to qualify for a series, and then a minimum of one game to win the series, and thats if i get a monster LP gain on the first win. please devs, make this a thing so players can get out of rankings they have outgrown without having worry about AFK and leavers since what is currently in place clearly isnt enough
