Alrighty, so I've been tanking as long as I've had this character and I'm quite comfortable when MT in 10/25m Naxx/OS [haven't tried EoE yet] and every Heroic. My build seems quite solid at mitigating damage and peaks at about 57% dodge/parry (which I feel is lower than it could be).

What I'm asking of you all is this: What do you see in my spec that needs improvement? What do you think of my gear? Where should I go from here?

Gear:
The World of Warcraft Armory

Talents:
The World of Warcraft Armory


Thanks in advance!
