Until the day you queue up with multiple people who are much worse than you, then you get no sympathy from me.
Like two games ago, one of my RL friends went like 0/11 top nunu, and another went 1/8 mid swain. Our jungler was great, but my Ezreal was only so-so (9/9, like 30cs above enemy AD carry) and between the both of us, we couldn't carry the game.
