Can we please do soemthing about losing 20+ lp in 4v5s

Riot can we please do something to loser the amount of LP lost during a 4v5? It is such a drag to try and carry a game when the rest of your team wont surrender and drag a 20 minutes 4v5 surrender to 37 minutes to watch them take drg, baron, then end the game. Then after the game see -20 LP for not being able to carry and outplay everyone in game. like 9/3/19 27k champ dmg and -20 lp. I know if too much is done people will find a way to exploit it but something like afkers loser 25+ period and those or stay and fight it out -10. yes some duos might exploit it but at least 1 is losing a lot of LP. Just a quick thought to see what others think.
