I don't understand this build at all. Sorry to say this but it looks like a mess.
Vampiric Assault is best used for Auto Attack build.
Tumble is best with hungering arrow build.
Storm of Vengeance is pretty useless against heroes. You never hit more than once anyway, as they run out.
If you need an extra escape, which you took Tumble for, you better take Bolt of the Storm at level 20 and a more usefull skill at level 16. Like Blood for Blood
