What follows is partly for my own memory, but also for people who I will be doing heroic instances with.  These are the last few "upgrades" I can get outside of a raid instance:

TANKING SET:

1)  [item]Signet of the Accord[/item]- drops from Sartharion in Obsidian Sanctum (10-man)

DPS SET:

1)  [item]Gauntlets of Dragon Wrath[/item] - drops from Cache of Eregos in The Oculus (Heroic)
2)  [Staggering Legplates] - drops from Ingvar the Plunderer in Utgarde Keep (heroic)

I won't be rolling "need" on anything else, aside from what I have linked above.

With the tanking set upgrades, I will continue to be uncrittable.  With the dps set upgrades, I will be hit *AND* expertise capped.

Thanks for everyone's time so far, I have enjoyed every heroic!  Hope to see you guys in groups soon!
