HI, my guide to you ;)
GUIDE NOT A CONCRETE BUILD YOU SHOULD FOLLOW EVERY GAME
YOU COULD CHANGE AN ITEM YOU DO NOT LIKE

With this set of items you will rip apart teams
Make sure you're not targeted and killed
SURVIVE > KILL!!! I HATE IT WHEN SO MANY NOOBS OVEREXTEND AND KILL THEMSELVES
if enemy gets away, HE'S GOT AWAY! DON'T TRY TO FOLLOW AFTER TURRET OR CHASE HALF WAY ACROSS THE MAP.
If enemy is chasing you run towards teammates!
Last hit always
Harass with volley then go in for the kill when they have 1/2 of health left
NEVER, EVER HIT TANKS! until u got madred and/or black cleaver :D
when enemies are not on the map use hawk shot when ever they are gone
Work with your team, don't ride solo, IT'S A TEAM GAME
Will update this build when I have more time on my hands, REMEMBER TO COMMENT AND TRY ATLEAST 2 TIMES BEFORE YOU VOTE
