I rewatched that one video (Warning: NSFW language), and it inspired me to make a level 11 build
Constantly refreshing THP from switching between human and beast form. Lots of different damage resistance, damage reduction, half damage, and effect removal (dreadnought FTW). Resists poison, shrugs it off like nothing. Lots of slow and prone, she'll will knock you down and maul you with her claws (bonus 1d10 with CA) and is a wicked charger (+1 to attack, +2 to damage). She's fast, agile, vicious, and will take a beating and keep on trucking.
She resists forced movement and can even burrow.
Ladies and gentlemen, I give you... the honey badger:
Resist 5 poison.
Resist 10 all damage on AP.
Resist 6 ongoing damage.
Reduce ranged and melee damage by 3 (stacks with resist).
Reduce all forced movement by 1.
Encounter, Stone Panoply: Resist 6 all damage.
Encounter, Scattered Form: Half damage from melee and ranged (stacks with resist and reduce).
Encounter, Barkskin: +3 bonus to AC (minor).
Encounter, Swarm Dispersal: Resist 10 all damage (interrupt).
Daily, Armor of the Wild: Resist 3 all damage for encounter.

====== End ======
It suffers from not having Con as a secondary, but Hengeyokai works too perfectly not to use.
