Pally tank wishlist from the first 6 bosses in Ulduar:

Here is my current Gear:
Valorous Redemption Faceguard
Boundless Ambition
Valorous Redemption Shoulderguards
Platinum Mesh Cloak
Valorous Redemption Breastplate
Bindings of the Hapless Prey
Valorous Redemption Handguards
Ablative Chitin Girdle
Valorous Redemption Legguards
Sabatons of Endurance
Sand-Worn Band
Signet of the Earthshaker
Essence of Gossamer
Repelling Charge
Last Laugh
Wall of Terror

Here are some of the items that I am looking for out of Ulduar
Flame Leviathan
Mimiron's Inferno Couplings-These are a definite upgrade over what I am currently wearing, my Bindings of the Hapless Prey can be relegated to my block set.
The Leviathan's Coil-is a better tanking ring Signet of the Earthshaker due to the avoidance, again the signet can go into my block set bag.
Titanguard-This is a very minor upgrade, once tanks who have a genuine interest in it have a chance I may consider taking it.

Razorscale
Dragonslayer's Brace-once these drop to me I completely replace Bindings of the Hapless Prey

Ignis the Furnacemaster
Chared Saronite Greaves-Definitely an upgrade, I give up expertise for hit.
Heart of Iron-Yes Please.
Plans: Indestructible Plate Girdle-More avoidance, definitely a win.

XT-002
Shoulderplates of the Deconstructor Definitely an upgrade and as a plus it moves me one step away from power ranger.
Signet of the Earthshaker-I've already gotten this one, as mentioned earlier it will become a piece of my block set.

Assembly of Iron
Handguards of the Enclave-A block set upgrade and sidegrade for single tanking. If I needed my current gauntlets to keep a T7.5 set bonus I easily would.
Plans: Indestructible Plate Girdle-See my comment above

Kologarn- Cache of Living Stone
Necklace of Unerring Mettle-A sidegrade for single tanking, useful for a block set.
Saronite Plated Legguards-Definitely an upgrade, I think you've caught onto my dislike for block for my main tanking set.

Auriaya
Platinum Band of the Aesir
Cloak of the Makers-The Platinum Mesh Cloak's big brother, easy choice.
Unbreakable Chestguard-Since the Paldin T7.5 Set piece is basically the lower iLvl version of this I would have to consider it.
Plans: Spiked Deathgdealers- A better piece than Chared Saronite Greaves, we get 2 gem slots to make up for 25 stamina ( win! ) and more avoidance instead of the hit.

So that's what I'm looking for in gear. I will probably find a way to keep my 2pc T7.5 set for a while until I get a chance to see some T8. I will be praying for those blacksmith recipes each time I go, I'm betting some will even be a money maker.
