I talk from my personal experience.
I play as blood with GoD
I have experienced a noticable boost to overal dps by using it.
In my current gear (2T9)
I have 5 procs to watch for: Fallen crusader, Banner of victory, Greatness, sigil, 2T9.
I'm confused; you came to an Unholy discussion and pitched your Blood Build; are you claiming your build in 2T9 does more damage then those listed in the OP (first page) ?
