I´ll make this short start with the build from left to right you can also pick vampiric scepter ealier and phage too. ealier atk spd means faster dmg on minions and champions with your w skill chase in with e 2 times and q to follow fleeing champs if u cant reach them cause of cooldowns use your ult.

pros:
nice chasing abilitys
off-tank
good at mid game and late game.


cons:
bad in early game
if focused from all 5 enemy champs, fast down.
without atk spd to slow to make enough dmg.


counter heros:

Darius, Singed



let me know if u like this build :)

updated guide a bit.
