Prime 32: Very well, dropping Great Cleave for Combat Reflexes.
Sadly, we need Improved Sunder as a prerequisite for Combat Brute.
Problem with Extend Rage vs. Extra Rage. Thing is, since I'm using the Whirling Frenzy variant, I don't get the Con boost Rage normally grants (The Frenzied Berserker's Frenzy doesn't grant a Con boost either) so I'm worried that the duration of Frenzy might be a tad short. Plus, if Frenzy triggers more often, this means that by the second time we enter Frenzy we will be exhausted and pretty much useless by the end of the first encounter (assuming we enter Frenzy twice) and need to wait until 20th level before we get Tireless Frenzy.
As for the Whip-Dagger, the build is meant to focus on a Two Handed weapon, so no carrying a weapon in our off-hand. Plus, we can't use any Psionic abilities while we're Frenzied anyway.
Bloody Initiative: Seriously considering that.
Already included some potential maneuvers in the above post. Nice suggestion on Boulder Roll. Charging feats that allow us to attack, move, and reposition are always good. What should I replace Boulder Roll with?
