BP of Ancient Steel or Ghost Reaver's BP?

I was sure BP of Ancient Steel was better for prot tanking until I saw on Icy Veins that the GhostReaver was farther down the gear list (even tho i-level is the same). Does the Ghost Reaver have better reforge/regem potential for us? Just want to doublecheck with you all before committing with the mats.

Thanks.

The ranking on the Icy Veins is by ilevel and then simply alphabetical, so I wouldn't worry: it's not contradicting your initial assessment. Ghost Reaver has a bit more mastery but couples that crit, which is the one stat we don't have much use for. Ancient Steel has a lot of dodge, which is still a decent tanking stat. I'd use AskMrRobot if you want to see a ranking of items according to some index of desirability (load your character, (right?) click on the chest and you should get a new screen with the upgrades ranked by the gearing scheme).
