Ah, I have been away from the boards for a while. Jason, thank you for posting. :) That is about how I had it figured. I honestly never really understood why two feats that are purposefully placed together on an archetype would be made to not work together.
Purple Dragon Knight: Ok. Seems as though we are on the same page here. FYI - in my son's character's situation he will be using a bardiche one handed via Phalanx Soldier and will have a shield in his other hand along with Two Weapon Fighting and Improved Shield Bash. So he will be good with covering his adjacent squares and threatening throughout his reach. Its a very Spartan build.
Also with the advice from this thread he will also be going for the Vanguard Style line of feats. Saving Shield was already part of his build so it is only natural and fits very nicely. ...it will require the buying of another book though.
So, with Jason's post are we all on the same page now?
