I've been reading a lot about barbarian tactics and keeping people from getting near you in the first place. I noticed that knockback was one of the things people were fairly high on. Between the knockback power and unexpected strike they could pretty much get someone out of their area and prevent a full attack against themselves.
Thinking on that I remembered that a character with the shield slam feat gets a free bull rush on anyone struck with a shield attack. Between his regular strikes, his unexpected strike and later on his dazing modified come and get me ability he's be able to prevent most full attacks against himself.
Is there a build out there for this? Would he be giving up too much damage in exchange for this?
No reason you couldn't two hand a Bashing Spiked large steel shield, does as much damage as a greatsword and with improved shield bash, you aren't losing anything on AC.

this can work, you don't need the Knockback Rage Power (cancels out with getting Shield Slam Feat) and you can use the trick all the time, i.e. even when you aren't Raging, and there isn't the 1/Rage limit of Knockback. FYI, you can make Knockback/Shield Slams as the AoOs that Come and Get Me allows. Strength Surge and/or Improved Bull Rush are useful for this tactic. Improved Bull Rush is a Pre-Req to get Rhino Charge, a great Feat from the Sargava Companion which allows Readying a Partial Charge while still using your Move Action.
