Bad players are the only players with impact
Good players, even if there is a skill differencial, aren't going to snowball a lane into a unrecoverable game. They'll gracefully lose the lane, not fall far behind, and maybe die to a few tower dive ganks. A bad player just default loses the game, because now there's a 9-0 Talon running around at 10mins and there is nothing you can do about it.
this game is in the toilet.
