Since our guild lacks a druid tank and we have a plethora of warrior tanks each with different gearing, I've opted to become the stamina stacker. As of now I'm up to 33.5k UB while maintaining 22.71/20.36/21.46 D/P/B. I've managed to maintain uncrittablity by using the PvP shoulder enchant Greater Inscription of the Gladiator - Item - World of Warcraft with +15 resil with 537 def.
With any new content, gearing for stamina/avoidance is generally better than TPS gear to help over come the learning curves, however, like many of you out there, I want to be as correctly geared as possible to help the raid perform their best.
Is there anything else I can do with my current gearing to prepare for Ulduar?
