This is one feat I wonder why would you like to take it, unless it is to be used with the other wolves of your pack. The idea of stunning someone with a punch is cool, but what benefit is there to it if you can't take advantage of that yourself? Unless you have somone by your side to whack him while stunned, the only benefit I can see is if you wined initiative, then hit him and stun him, he can't attack you that round, though he will be back in posession of all his faculties next round. I don't think you could still ready an action (another attack, or whatever) against him, because you already took a standard action. Well, I don't know.
