Should be able to leave if a player afks for more then 10 min?

Ok i hate 4v5s. They are not fun, they stress me out, and i feel like i actually become a worse player after being in a long 4v5 match. I am in low priority que for leaving a game full of feeders and one dc. ( I didnt feed or say anything toxic) So.. why the fuck isnt there a timer that automatically starts a ff vote after 5 min of a player being non active ? YES people get dc all the time and reconnect. But a lot of times depending on where you are in the game that 5 min can cost ya 2 towers and a team fight. Lots of games where all 4 of us are over it already and we are running around for 15 min wishing the game was over. It should be up to the players if they want to waste their lives or not. On my new account i have a 55 percent win rate with panth over 200 games. Its safe to say around 80 percent of my losses are due to people randomly afking (Which is totally fine in normals) In these games if we are not destroying the other team...i want nothing to do with it. Usually ill just farm untill 20 hits and if the FF vote fails ill just afk.

They also can have a que where you finish other peoples games if they have an afk. You would start exactly where the other guy left off, same champ and same items. If you "accept the mission" you can get differant amounts of elo depending on where you are in the match and how much you end up doing. Would it create pressure type situations where a team asks a person to leave ? Probably Do people currently tell bad and/or afk players to go kill themselves? Yes they do So the current system is a playground for toxicity already so I think its about time they make some changes.. Will it be abused? Maby Does the report system get abused? Lets say riot has a country size lot full of computers with reports stashed away to never be read.. What do you guys think ?
