Some small words ...
This is the hero overwhelmed 've ever seen ... if you have a team that follows and is joined up to level 6 ( also doing what he requires map ) , you will not have problems to win the game .
Already from level 7 you just the combination of :

Chain Lightning Q
Feral Spirit W
Windfury E

I propose for the final Earthquake ( R ) because there is nothing better than slow down the entire opposing team to be able to attack and massacre !

Enjoy it!
