Can We Please Reduce the Amount of Influence One Feeding Ally Has in Deciding Games?

I am so tired of the fact that it takes more than one player carrying to win, but all it takes is ONE heavy feeder to cost an entire team a match.

Can something be done about this?

Perhaps surviving allies could receive bonus experience and gold off champion take downs while an ally is dead.

I don't know.

Or maybe allies who die often eventually grant the enemy team no gold and experience for the kill.

I honestly don't know.

Just please do something about this.

I am rarely capable of carrying allies who literally die every 2 minutes or less in game.

Eventually my performance, no matter how well early on, slips because I cannot fight off the fed opponents who feasted off some of the worst players with whom it has been my displeasure to play.
