Second post!
Anyway, Armored to the Teeth was mildly nerfed to 2 AP : 360 Armor, which makes it worse for Prot Warriors (no SBV) but as good as it was with Kings for DPS. As I note in the thread, it's still not even close to enough to make up for the massive difference in stat totals between Plate and Leather, but it's not a horrible change.
More to the point, Thunderclap had the threat increased and now _hits an unlimited number of targets_, which is pretty huge as we can actually, you know, AE tank large packs now. It's been a long, long time coming but we finally got it.
Revenge and Shield Slam also got some degree of damage boosts, and Revenge can now proc Sword and Board. How strong these changes are remains to be seen, but this is a rather nice fix to round off the issues Prot still had. We'll see what they do with Arms and Fury.
