This build is good for gank / tank / turret destroy / kill and escape, im using it actually and its good and different. this build also based on cooldown of spells, you first jump with E, then buff W and attack with Q, reducing E and W cooldown to 1 second, then 1 more attack and jump again... making a cicle. ur ultimate reduced cooldown too, so if u stay long in fight u maybe use it twice, or one time at mid and another gank at bot/top... mana regen is good to non-stop combo (E W Q) !
