I'm surprised you didn't mention the Champion path at all, it has several very nice abilities. Clean Blade is good for crit-fishers, Precision will bolster up your full attacks, Fleet Warrior is move+full attack as a constant, Critical Master follows up on critfishing builds wonderfully, Shatter Spells is basically a beefed-up arcana, and I even had an idea that used Sweeping Strike with a whip while polymorphed into a Huge creature for maximum reach.
