in my offspec gear atm - apparently being so close to exp cap is actually more beneficial that reforging to go over cap, according to ask mr. robot, though I suppose over exp cap isn't so bad as your white hits give runic power (thoughts?). planning to pick up legs for 2p dps bonus - not sure whether or not I should step down from 372 gear to get 4 piece - heroic helms are obviously going to mainspec first.

edit: to 3nfy.. i would take a review of your reforging/gemming. You seem to follow an inconsistent avoidance/mastery approach. I'm not one of these ppl who spout that mastery is the be all and end all, but i think you should be more consistent in your approach - at the very least it helps you think about what you need to do while tanking - i.e. do I really need to be focused on gaming RE procs.
For example: you don't reforge any of your hit on your helm into mastery (or parry) yet you gem for mastery. I would either reforge the hit to parry and gem dodge/stam or reforge to mastery and leave gem as is. Same with chest - why not reforge out of mastery into dodge?
