Wow, some of those general feats are great. Vexing Flanker, flanking an enemy makes that enemy grant combat advantage to your allies and Two Weapon Opening, which lets you make an free action offhand attack if you crit with your main hand weapon are both perfect fits for my rogue. My Warlock and Wizard will both love me for Vexing Flanker (saves them a feat from Distant Advantage in the very least) and being a Two Weapon Fighting Daggermaster means I can count on an extra attack every 1:6.66 attacks... Fun times.
