This is tough to answer, so I'm going to give a very rough answer.
You are one of the top PVP equipped Warriors on these forums which is probably why no one has responded to this thread. You aren't wasting sockets and your gear seems up-to-par. Spec seems standard as well.
The only possible suggestion I have is raising your Crit next before too much more Attack Power. I may very well be dead wrong by making that suggestion, though.
Hopefully by bumping this someone can see this and give a better response than I have.
