how 80% of the games go

So you have never feed before maybe ? Everyone can have bad game you know.

I go even or ahead in lane and my team proceeds to feed and I cant do anything and go negative trying to help

emphasis added. It basically comes down to this: if you genuinely believe that you are going negative trying to help teammates, then the obvious solution is to stop helping them! For real, if that Lee Sin is 1/9/4 and says, "come help me." You throw down an exclamation mark ping, turn your champion around, and go someplace else. It isn't personal. It's just common sense. Just like if your 9/3/1 Zed says, "let's do this," then you ping on the way, and you do that.
