love how you say to follow these rules if you like losing. Because learning multiple champs in case your main gets banned is a bad thing and queue into a match when your already is a horrible mood will have no effect if your team starts to lose *cough*. Some of theses are unnecessary but I wouldn't say they are bad.
Rule #11: NEVER give your favorite role to someone else if you're higher in the pick order. They WILL suck at it, feed, or outright disconnect while you took support instead of mid. Being the nice guy will ALWAYS come around to bite you in the ass.
