Change your Solid blues to Puissant greens, get the stam enchant to chest, craft a tank helm, get tank gloves, change your boots enchant to Lavawalker, get rid of the +expertise gem in favor of another either parry purple or fractured yellow, grab the rest of your enchants, 9-24 friends, and head to Firelands. En route, trade your Impetuous Query for the tol barad mirror trinket if you're exalted. If not, a moonwell phial from the firelands, Symbiotic whatever from Magmaw, whatever you can actually get your hands on. AND FOR THE SAKE OF ALL THINGS HOLY, get rid of the rogue throwing weapon and get the Deflecting Star. Now that gear's out of the way, I'll leave the spec to someone more accustomed to warriors.
I'm way better at holding my liquor than a panda.
