Path of Exile: Scuffed Herald/Purposeful Harbinger Abuser Build

So after getting squashed and depressed by a failed Uber Lab run, I waited a few days for prices to come down on Voices and other gear. Ended up buying a few more Purposeful Harbingers, two 7 passive Voices, 1 Purposeful Harbinger/Heraldry and 2 Call of the Brotherhood rings (corrupted). How is this looking so far?
