If you lose your lane regardless of a jungler there and you feed
You are a BAD player. Its not the junglers fault that you are dog trash at the game. If your jungler doesnt come to your pushing lane where you solo die constantly chances are he knows you suck and wants to either help other lanes or farm because there is no where to gank. However you can blame your botlane for being so terrible that they lose lane in 5 min and go 1-10 because yes that IS their fault nobody elses.
The only way you can blame your jungler is if you are ahead,not feeding or doing well in farm without dying while having a lane push into you. If your jungler is up in farm and kills/assists while doing what he can while you all feed you bitching is just saying you are an insecure little pre teen that cant handle how shit you are thanks to riot :D
You can never blame if you die 6x average per game. I die 4x average per game and thats still too much. Everytime I die like 6+x a game im either giving up because im playing like shit and tilted or an unlucky game. Otherwise I either win or dont die that much. Cant blame someone for not being a feeding bad player like you are lul.
