If you need a build for Shifter Racial lives, try this one.
3 Rogue/17 Barbarian
Wildhunt Shifter
Take enough Strength for Power Attack at level 1, Con 14-16, and put the rest in Dex.
Take all 3 Rogue levels first to get the second Thief Acrobat core for Dex-to-damage with Quarterstaves.
Take THF, ITHF, GTHF, IC: Bludgeoning, Completionist if you have it, etc.
For heroic leveling, I go Ravager for Blood Strength in tier 5. Thief Acrobat has some good stuff, as well.
