So, I revised the feat trees based around combat expertise and bodyguard to be a little more dynamic and fun and to actually something that I think people might use. I gave them all unused feat names so that they are just new feats even though I think they would effectively replace those trees. I am just looking for thoughts on if these feats are interesting, or terrible or too good.

Multiple attacks from a single enemy against a single ally provoke only a single attack of opportunity.

Man, these feats are legitimately cool. I am a pretty big fan of them! I can see them working amazingly on a 3rd party class known as the Warder (The Warder gets Combat Patrol at level 1 basically).
Good stuff here.
Typo: Defensive Expertise: "Beginning"
I am iffy on Impregnable Defense. Secondary attacks and minion attacks are going to buff you. It may be to good. But three feats to get it may be the counter balance. I like what I am seeing here. If you get a chance to play test them, let us know how they work out.
