Ready for Raid Tanking?

As the title suggests, I was wondering if my tank set/spec is ready for raiding.

Please check out my Armory Profile and comment on anything that I could improve on! :D

Things I'm working on:

TB Tokens for Mirror of Broken Images

a weapon with mastery (Sword of the Bottomless Pit, Jeklik's Smasher, Reforged Trollbane, etc.)

gear from ZA/ZG

I would glyph Rune Strike instead of Death Strike since you're usually not sitting on a lot of RP for a long time.

I'd also gem Fleet (+54 mastery and run speed increase) instead of Austere.
