Rage tanking is in a weird place right now. Both as a tank and as a DPS in runs I've noticed a certain amount of squishiness that wasn't there before, both due to certain abilities being fairly hard to use (Both Shield Block and a full Shield Barrier are expensive, costing 60 rage) and the loss of a lot of passive mitigation we were all accustomed to. Apparently the devs have noticed it too: Ghostcrawler posted these changes coming for rage warriors on live and the beta fairly soon.
The rage changes are nice (druids will now get 10.85 rage from an auto attack) because they'll allow for rage tanks to be more often using their active mitigation. Honestly, high incoming rage really isn't an issue for tanks, since we don't use rage abilities for threat anymore (with the exception of rage bleeds like Heroic Strike or Maul) as much as we do for survival.
What impressed me was the change to Thick Hide and the Defensive Stance/Unwavering Sentinel changes. Were they warranted? Absolutely. Warriors in particular have been the squishiest tanks since the patch, with druids not far behind, and this change will help even out some of that sustained damage that erodes healer mana and thus, our lives. This is me, being happy over here.
