Feedback appreciated.

You are mixing Physical Damage and Elemental Damage, would probably be more efficient making a choice. Don't see the point of grabbing Ondar Guile + Iron Reflexes. Revenge of the Hunted seams really bad when you are already at Life and Evasion nodes circles at Scion start area, where you could made much better use of your points. Rebuck of the Vaal seams really bad when you could make use of a rare Thrusting One Handed Sword for higher range and faster attack speed and scale it with Anger and Wrath auras.
