Does your DM allow warshaper? Nearly every ability mimics or is better than an epic feat. I hate the class and think it was definitely created for powergaming munchkins, not saying you are one but the designer certainly seemed to have that in mind.
I'm pretty sure your build isn't typical but its definitely powerful, especially since you will be in bear form alot.
In bear form, the character still has the option to grapple and do damage as per an unarmed strike. One advantage is iterative attacks, and the character will still be able to do any type of damage (slashing, piercing, or bludgeoning.)
Plus it's sometimes inconvenient to turn into a bear. City adventures are a prime example.
The character doesn't acquire a bear form until 8th level, and I wanted an unarmed build that was viable from 1st to 20th.
