Suggestions on a Bruiser build?

[hellz]

I have maxed provoking strike and the stun skill. Lot of skills dont seem good so I have points to spend. What are the one or two must have skills for a bruiser?

Just finished my run.
I found that damage-dealing and stunning abilities (Ground Slam/Wild Pummeling) work better for me than abilities focused around being a tank.
My Bruiser was also a Chemist, and I used Incendiary Grenade extensively throughout the game (it also helps if your Bruiser is Rooted)
