Easy champs shouldnt carry games....

I understand that "easy" champs exists for a reason. They are cheap and good for learning the game. I don't want to see easy champs changed to make them harder, but i feel that they shouldn't be able to carry games as hard as they do. It's ridiculous seeing total faceroll champions completely demolish games with no real combos. This creates an imbalance in the roster of champs and how they impact the whole game. Champion's like Master Yi shouldn't be able to win games and 1v5 all by himself. Learning champions should produce the amount of power that you are willing to invest in them. Champions that are noticeably harder should create more of an impact. This is more of a personal issue though because I play a lot of Lee Sin and i have been destroyed by the biggest faceroll champions like Master Yi, Xin Zhao, Tryndamere, Fizz, etc. I should have a greater impact with champions like Lee Sin than some stompy champ that requires a keyboard and no knowledge to get an easy penta. The people that actually put in a lot of time and effort to learn a champion with unique mechanics that take a lot of practice should not be completely destroyed but another champs' mechanics alone (not skill). If I attempt an insec play with Lee Sin, the last thing i want in Yi to Alpha Strike me and go into a mini Zed ult and make me look like a dumbass. Easy champions should be there to help newer players learn the game, not to stomp higher elo games. There should be a balance between the effort a champ requires and the carrying potential they can have. This can reduce the bullshit that the easy champs have and make the game more of a skill game than a match up game.
