Elusive Target is the tactical feat from CompWarrior that lets you do some really cool defensive stuff:
1) your Dodge partner gets no extra damage when Power Attacking you, but still takes the attack penalty,
2) if you're flanked, your Dodge buddy automatically misses on his first attack and instead whacks at his flanking helper (who's flatfooted!),
3) if you provoke an AoO from moving, you can make a free trip attempt against anyone who misses you.
Once I got Midnight Dodge (which is a carbon copy of Dodge that stacks), I could designate two Dodge partners and it got super fun. As a crusader, you frequently have move actions available. I used them to move around, soak up/waste their AoOs, and pop right between them to give myself infinite AC against their first attack.
If you stack on Iron Guard's Glare with that, then your enemies are left with the choice of only being able to Power Attack your allies with an extra -4 to hit, or not use Power Attack on you. It puts monsters in a position to make awkward decisions.
