I have a suggestion for competition:
100. Don't forget to have fun.
Having fun doesn't mean griefing, trolling others, testing builds, or feeding in ranked. That's not what I mean (yes, that is fun for some of you out there, I know that.) What I mean is, if you love the fight, if you like having the deck stacked against you, if cranking up the difficulty gets you going, then that kind of mindset can really help you win. I have to laugh when I see people moaning about how hard it is to get Elo. What if your self-image is based upon core knowing badassery instead of what other people think about you? Wouldn't it be easier to relax, have fun, and stomp other player's faces with gusto?
