I know there are certain items I need to upgrade they just haven't dropped yet in 25 Man Naxx, I guess I'm more interested in making sure I'm using the best gems and enchants or if I am messed up in some place
Also which pieces of gear that I still need to upgrade should I be aiming for.
Hard to quibble with your gear... I'm no where near you gear wise. But if I were in your shoes there are two routes I would consider, both involve rolling back some of that hp.
1 - I would change chest and shield to +defense, and swap repelling charge for a threat trinket. You might need to change the yellow socket in your belt to def/sta gem too. You can always swap it back in for fights where you really need it.
2 - I would regem all the red gems to guardians and change the bracer enchant to +15 expertise. You're at the expertise softcap but that's still only about half way to the hardcap, so you are still getting parried quite a bit.
I don't have any threat issues right now so I don't think I really need to swap out my defensive trinket for more threat trinkets and 2 while going after the hard cap for expertise is an idea I have yet to see any tank actually chase that beyond the 2 examples given in the HIt and Expertise thread in the Gear and Enchanting forum.
Also, and i may be wrong here, I think 32k is going to be about the min amount of health unbuffed a tank is going to need for the new raid zone in 3.1, does anyone else have any thoughts on this
