Morale is important, here are some tips to keep it up!
Morale is a very important ...thing... that you should be trying to keep up as much as possible! Wars have been lost over morale, but don't worry, I'm here to tell you how to prevent losing these wars!
Tip #1: Don't flame your allies! I know, I know, YOU are the best mid laner that exists at the moment currently, but if you flame someone who takes your destined role, they're going to do even WORSE than you had originally anticipated! (Which is pretty bad!) If you don't say anything, or even give some friendly advice, you might notice your win rates going up, summoners! ;)
Tip #2: Blame yourself! Sure, it's probably all your junglers fault even though he's ganked 4 times already, but honestly, he is probably bad at the game and wouldn't have helped, you are much better and don't need help! So don't yell at your teammates for doing things you can do!
Tip #3: Listen to other players! If you let these little peons strategize for themselves, they're going to think they're almost half as good as you are, and when that happens they start PLAYING half as good as you are! This will increase your chances of victory much, much more!
Tip #4: Never tell someone if they did something wrong, they're egos are just as big as your ego, and Riot frowns on that kind of stuff, which is why you were chat banned 5 times in the past! Sure, you might have been pretty blunt, but you know what they say, "Negative reinforcement is best reinforcement!" And reinforcements are a very important thing in war!
Tip #5: Drink your own piss.
