Blood moon frenzy should effect you.
Acrobat speed: Its been throughly tested, Acrobat II only ends up with a total of +15% from haste (the gear and monk won't stack, those are enhancement bonuses, and these won't stack with haste. Or at least this is how it should be with the enhancement bonuses).
15-20 comes from the base: 18-20 with improved crit is 15-20. 18-19-20, 15-16-17.
What you mean there is you are attacking at 180% normal speed, or 80% faster. You do not apply your full STR bonus to offhand attacks unless you are a monk using handwraps. This is how its been for a long time. I'm sure of this.
I want to know what makes the TWF attacks so much better than wolf forms attacks as that seems to be implied, not how the style works. People keep saying that the attack damage is cruddy, but TWF isn't, why? As I already pointed out, a full doublestrike setup from feats and/or destinies gets pretty close to how many attacks TWF gets.
