One thing i think is a little bit stupid, is that you bought the 264 Relic instead of just useing the 245 one. The 245 one gives 200 dodge INSTANTLY, meanwhile you have to build up the stacks on the 264. That means, if you just stand for like 15 secs, doing nothing (some does on Saurfang etc.)
Id recommend you to buy the 251 tier 10 tanking shoulders, Buy the belt from badges (Vedegris, or whatever its called) and the 264 hand from badges. Get the 264 boots crafted, (Boots of the Kingly Upheaval)
After that i would recommend you to buy the 251 tier 10 helm, for the 2p tier 10. Else your gear looks pretty neat.
As stated b4, change your 10 stats out with the 15 stam 10 agi.
I would say, that you should try do ToC 25 till you get the Juggernaut's Vitality (192 stam ftw.)
Else, don't aim to high for the VoA runs, there never drops anything you can use.
