Can we realize something for a second?
10-10-0 isn't being "good." All you did was give their team shutdown gold. Running to the back line and dying for 1 or 2 kills (at best) isn't showing that you're good. It feeds more gold than ending a game at 0-10-1.
I'm sure you're all going to look through my match history and claim that I do the same thing. Well, I do, but I also don't claim to be amazing on top of it.
