Mid. Windrun will be a great escape tool for the majority of the early game, and makes you evade all physical damage. Powershot fires in a straight line in front of you and travels a very long distance, use it to kill creeps while ideally hitting the enemy mid as well. Shackleshot applies a weak stun, but it becomes a very long stun if the target is near a tree or enemy hero when you use it. Exploit this by blinking into an enemy when they're near a tree or hero and shackle them. Focus Fire is a very strong single target ability when used in tandem with windrun but be wary of Blademail and Centaur Warunner.
