I've managed to rack up 150+ Emblem of Triumph, but i'm not quite sure if it's worth dropping my T9 Bonus(iLevel 232) for non set iLevel 245 gear. If it's not really worth it, i'll probably go for PvP gear, don't really play tanking on this toon as I don't have a scoobies how O.o
At a glance, buy Mirror of Truth instead of Victor's Call. I'm not really sure on how much 4 set bonus is worth, if it's meh at best get the Ilvl 245 helm.
Also, you're way way waaaaaaay over the expertise cap for DPS
