Its ok, I'll play West EU from now on, I always swap between the 2, Blitz is good for laning and ganking, his pulling ability can be good for pulling enemies into a teammates ult or a turrets line of fire, or when your chasing you could use flash or ghost followed by pull then his other moves to finish it off, and if you keep chasing, your pull will have its CD removed and boom u can just do it again, I like to pull squishies early game.
At the start pick a lane with a squishy, let the enemy team push ur lane to your turret, run fowards pull an enemy past the minions 2 ur turret and use exhaust, they should try run off, then use ghost and chase with a teammate for first blood :P
Going to log in now, may need a bit of work though, bit rusty
