I will always do the opposite of what you say if you're a jerk

Don't misunderstand, if you give direction or advice, and it's right, i'll listen all day long. But if you say things like "omg, you suck so bad, FOCUS THE ADC NOOB!" I'm just simply going to do the opposite.

You might say "but then you will lose!" But guess what, this is a game, and winning isn't my prime objective, fun is. If you go out of your way to be a jerk and ruin that fun, don't expect me to comply.

Just an fyi, if you want people to do something, have some common decency, because there are plenty of people who would rather lose than give you the satisfaction of being a prick.
