Well by and large Frost is going to want pretty much the same gear as Unholy. There might be some exceptions but it's hard for me to work out what they are without any stat weights for the spec, and when I searched the Frost DPS thread there didn't seem to be any.

I'll set about updating the OP to a new set for Unholy/Frost using Tier 8. Blood remains unchanged. I'll also get working on those 'expertise/hit capped' sets.

edit:
Is 4pc Tier 8 now good enough for Unholy to retain the bonus instead of using both Warhelm of the Champion and Plated Leggings of Ruination (both of which on their own are clear 'Best in Slot')?

edit2: I've made a preliminary update to the OP's Unholy/Frost set. For now I've changed out the T8 helm and ignored Plated Leggings of Ruination. The thinking behind that is that - assuming keeping the T8 bonus is desirable - then the T8 helm is pretty terrible whereas the leggings are pretty good, so I think it makes more sense to swap out the helm even if it that means ignoring the rather amazing PLoR.

The set bonus may well prove to be so marginal that it actually ends up optimal to ignore it and go for PLoR anyway, but I need someone smart like Methods to confirm that.

Well at least in single target the raw value of T8 4p plus the [Warhelm of the Champion] should be worth more dps than 4p t8 plus [Plated Leggings of Ruination]. The issue is that it may be really difficult to juggle that high amount of hit from the Warhelm. If you end up with the [Earthshaper], for instance, instead of [Worldcarver] (or [Voldrethar, Dark Blade of Oblivion] obviously) you will be overcapping hit with many other 239 BiS items. Just something to think about. Kind of solves our Expertise problem though.

To answer your question directly though, yes, T8 4p plus the Warhelm should be the best combination without wasting any of the stats. Were talking an extremely marginal difference though (maybe ~0.3%).

However, yet again, finding a way to combine the Warhelm and the PLoR should be slightly better than T8 4p but I'll need to do more testing on this one to make sure this is error free.Edit: Nevermind regarding breaking T8 to 3 pieces, it's very close but below by about 0.2% vs Warhelm+T8.

Ganashal - Thanks for pointing out my mistake. As you said it doesn't affect the point about whether 4pc T8 is better than 2pc plus BiS alternatives.

Methods - Thanks for looking into that. Using your Unholy stat weights, I get the following results:

• T8 helm is not even close to Best in Slot so is an obvious candidate to replace
  T8 shoulders are very slightly worse than the near-identical [Shoulderplates of the Eternal]
  T8 chest is BiS and provides valuable expertise
  T8 gloves are BiS as long as you can make use of the hit; [Gauntlets of Ruthless Reprisal] are the next-best alternative and are hit-free
  T8 leggings are second-best to [Plated Leggings of Ruination], but it's a reasonably distant second place

As Methods has confirmed, breaking 4pcT8 to make room for PLoR is a tiny DPS loss. However if you could make the hit up elsewhere, for instance with the Algalon cloak or Bladebearer's Signet, you could potentially drop the gloves and leggings for their alternatives, which would probably result in a small net DPS gain. I'll have a tinker and see if I can come up with something for Methods to test yet again.

Norg, are you not including Algalon rewards? Because the 25 man reward blows that one out of the water I found it at 370 dps approx compared to 310 from the faceless. (For cloak)

(10 man reward is also an upgrade of about 20 dps)

I understand. I have a spreadsheet with the values put in all nice and neat, without the hit rating on the cloak it falls roughly 14 dps behind the faceless cloak. Hit rating doesn't suddenly become worthless either, but 10 man Vezax will be a lot easier to get than Algalon anyways hahaaaa..... (I don't expect I'll ever see him dead)

Unholy possible BiS

Assuming your race is Human and with Draenei Aura this is the best I can come up with for alliance. This would change dramatically as an Orc without the hit aura (switch in Strength of Hodir?)

**** = Bold Dragon's Eye

Conqueror's Darkruned Shoulderplates
Plated Leggings of Ruination **** +Monarch Topaz (inscribed?)
Conqueror's Darkruned Breastplate
Conqueror's Darkruned Helmet
Conqueror's Darkruned Gauntlets
Belt of Colossal Rage **** +Monarch Topaz (inscribed?)
Armbands of Bedlam
Battle Lord's Plate Boots **** +Icewalker Enchant
Wrathstone
Darkmoon Card: Greatness
Sif's Promise
Seal of the Betrayed King
Insurmountable Fervor
Drape of the Skyborn
Voldrethar, Dark Blade of Oblivion

All the rest are obviously gemmed STR.

You'll be a fraction over hit cap with the aura and a little below Exp cap. Uses almost all 239 items.

How does using 2pcT7 + 2pcT8 look?

Using the aformentioned unholy statweights the T7 pieces still seem to hold upp decently well and looking at the stat distribution compared to T8 they seem to be almost the opposite so you could pick two 'good' pieces of each set and get the double small bonuses.

Hey Methods, I agree with your BiS for human DK, but I was wondering if you could shed any light/math on [Wrathstone] vs. [Bandit's Insignia].

I was still planning to use my Bandit's. I imagine I'll just sit with the Bandit's for the foreseeable future because there doesn't seem to big a well suited passive dps trinket for my taste out there yet. Armor pen on the [Mjolnir Runestone] is just meh for an Unholy DK.

Trying to build an Unholy set around the proposal that Worldcarver is > Voldrethar with the Orc Racial. This build meshes together pretty well, capping hit and expertise, only wasting 10 expertise, which according to the statweights still makes Worldcarver ever so slightly better than Voldrethar. I think there's still a few significant pieces that have yet to be discovered (most likely off Algalon himself), especially a 244 DPS weapon with 3.6+ speed...so this is probably a moot point, but oh well.

Helm: [Warhelm of the Champion] *Prismatic
Neck: [Insurmountable Fervor]
Shoulder: [Conqueror's Darkruned Shoulderplates]
Back: Drape of the Skyborn **Socket Bonus unknown, possible prismatic slot
Chest: [Conqueror's Darkruned Battleplate]
Wrist: Armbands of Bedlam
Gloves: [Gauntlets of Ruthless Reprisal]
Belt: [Belt of Colossal Rage]
Legs: [Plated Leggings of Ruination]
Feet: [Battlelord's Plate Boots] *Prismatic, Greater Assault enchant
Ring1: Seal of the Betrayed King *Prismatic
Ring2: [Crazed Construct Ring]
Trinket1: [Darkmoon Card: Greatness]
Trinket2: [Bandit's Insignia] or [Wrathstone]
Weapon: [Worldcarver]

Hit Rating: 266
Expertise Rating: 142, 17 expertise + 5 racial + 5 from RoR = 27 expertise

Thanks for that 'orc' Unholy set, I'll link it in the OP if that's ok.

I've made some fairly major changes to the OP today, adding different sets for different conditions and priorities. Hopefully it will prove beneficial.

I apologise in advance if this thread is meant to be limited to weapons/gear obtainable through PVE only, but I would like to find out how the Furious Tier1 and Tier2 weapons compare to Ulduar weapons in terms of PVE dps. A lot of the itemization budget is spent on stamina and resilience, but the weapons themselves have two gem slots and a massive top-end/slow speed. Could someone rank them roughly against the other weapons of the same level available in Ulduar?
