There should be a loss forgiven if a player on your team was feeding intentionally.
Everyone is level 30 knows the frustration of ranked. The biggest reason of frustration is when you lose because of a troll. This is how it works: You win a game because of a great team. The next game you play through laneing phase when one person gets mad at another and decides to feed. Or even better, they start the game with the mentality of feeding. That is the one and only complaint i have for the League community. Riot should make it to where, when someone is feeding intentionally for a long period of time and is showing NO improvement, that they are permanletly banned. Sound good?
