Skip fracture. It's overpriced in general and becomes even worse comparatively if you off tank.
Until you get Goring Blade (54), it still represents a DPS gain, as the potency per GCD is higher than your highest-potency combo (220 > 203).

The math is a little skewed when you get Goring Blade, because it becomes your highest potency combo even without the DoT in 3.2. The DoT's efficacy only counts if it runs at or near its full course, so if you're going for full DPS (which, OP, should only be done if you have a comfortable enmity lead in most content), the potency-per-GCD translates to roughly 150 (FB) + 230 (RB) + 240 (GB) + 150 (GB DoT - one tick per GCD) = 770/3 = 256.67 potency per GCD. So once you get Goring Blade, it becomes a DPS loss, but until that point, it still-potency's both Rage of Halone combo and Riot Blade combo.

I also need to confirm what you're saying about Protect. I could have sworn that the PLD version only buffed Physical Defense, but I may be wrong.
