Yes URF is for fun but that doesn't mean you should throw the game.

I'v been getting this in my games recently: :"Hey maokai if you fight with us we can probably win."(carrying the game but needs peel) :"URF is for fun. Who cares about winning?" (Running through the enemy jungle failing 1 v 2s.) :"Winning is fun too though..."(realizes not getting peel)

Yeah. The game mode is for fun but don't make it a bad game for the other 4 people you are playing with.
