I think the fact that Bronze through gold are basically the same thing is why your game is awful

I mean lets be real here. I have a harder time playing games in bronze than I do in high silver. When I'm in high silver I have team mates who know what they are doing (generally) with the occasional boosted person. In bronze, I'm not even surprised by the fact that my cs is 10x that of everone on both teams, but the botlane has died 10 times in 10 minutes so me carrying is probably not gonna happen.
