Want to win games? - Here's how!
Learn how to jungle. Get Thunderlord's Decree (What a shock), take someone who has a lot of utility and damage at level 2 (Lee Sin, Udyr, Pantheon, Rengar, Nidalee, Elise, y'know the drill). Look at the enemy jungler, and guess (with the help of a ward from a laner) what side they're starting, and if they start a buff. Usually, they won't. So you start a buff this time, get level 2, and then run your merry little butt over to their buff and kill them as they're taking it. They'll have low HP and it's an easy way to force a tilt. In fact, I just did it as Udyr (Tiger stance op), and forced their mid to afk and their jungler to go on a racist rant. The rest of the game was verbal abuse and counterjungling to keep the tilthour strong.
Happy New Year, and enjoy that fine, smelly cheese! <3
