It seems like a few warrior enchants haven't been updated for 4.1. In particular you guys are still recommending the "tanky" ones with dodge/stam, but mastery is much better.
Arcanum of the Dragonmaw > Arcanum of the Earthen Ring > Arcanum of the Stalwart Protector
Greater Inscription of Shattered Crystal is also now viable. (RAWR actually tells me it's better than Unbreakable Quartz but I imagine that is highly gear/content dependent.)
