Looks like a solid list. Pivot issue I could see, is that you lack anything super-speedy which can sneak around enemy lines, which is hard for pure Bloodbound too do.
You'll need to have a plan for dealing with gift from the gods, or places of power missions, where you need to potentially get past a wall of troops quick in order to contest an I objective, or Assassinate a hero.
I personally like an msu approach to blood reavers. I'd go four units of ten. Then you have more freedom of movement, and potentially more flexibility in the order of combats in the assault phase.
