It is advised that you use quickcast! Also, please read the notes for the talents: what is highlighted may not be your best choice!

tl;dr -
Go mid but the offlane is acceptable.
Bring a buddy in the offlane, try to crush the lane with them

End the game as soon as possible, if you can't farm the entire map.
