Tired of feeding team mates

Every single game there's at least one person who goes 0/5 by 8 minutes and ruins the game for 4 other people. People play their lanes as if they still had 30 armor and 30 MR runes. They overextend without warding, they die to obvious ganks or try to fight their laner 1v1 at severe disadvantage, and they continue to do it over and over again.

The game isn't fun when it's over at 8 minutes. And that's not the fault of runes, or over-tuned champions. It's the fault of that one single team mate who continues to make bad decisions and feed.

The best thing you can do for your team is not die, even if it means losing your turret. When will people understand this basic concept?
