Ever have a game where you just want to reach through the internet and strangle the idiot on the other side?

Graves (who I'm supporting with Lux) goes 10/0/2 during laning. Largely due to my effort (he only got 1 kill when I didn't feed it right to him). He then proceeds to quickdraw into the middle of each teamfight and die, losing us the game. We kept telling him to use quickdraw to escape/reposition, but he WOULDN'T LISTEN.
