Only quick suggestion I would have regarding the blood spec is to take one from Virulence and 2 from Unholy Command and put them into Ravenous Dead. Your ghoul will dish our more dps while he's alive, and stay alive longer with the higher stam bonus. That, and the 3% Str bonus you get translates to more parry and AP.
Edit - I would also take the points out of Butchery and put them into Abomination's Might. Full group buff, plus more Str for you, for the same reason listed above. I really don't think you'll be RP starved with this build.
