Very nice build that I also use. In your Game Play section I would add the following talent combo : When you take "Paralysis", "Lost Soul" and "Overhelming Affliction", you are becoming a nightmare in team fight. Your Shaddow Dagger becomes almost always available and when it spreads, all enemy hero get the 6% slow. This and your basic attack stack very fast and, if you manage well, you can very often slowdown the all opponent team by 30%. Again well done...
