I've been trying every possible talent spec / gear combination as DW Tank I could imagine / have the gear for. I'll go through them one at a time.
Except Blood and the Unholy specs detailed below, I tanked every 25 man boss. Parries were not an issue and I am usually hovering at around 70% avoidance - more or less depending on RNG. Had fights where I ended up with 21% of the time being hit. Therefore I would avoid going into gear / survivability discussions as I do believe most of them have already been covered.
What I do want to talk about, though, is my experience so far as a DW tank in 25 mans and what I managed to understand / discover spec wise. Read through, Unholy proved to be quite a big surprise.
Common talents used in all build combinations:
- Blade Barrier
- Bladed Armor
- Toughness
- Nerves of Cold Steel
- Anticipation
No spec was built without the above.
1. Deep Blood (51 - No DRW)
- lowest threat of all DW builds tried. fully (10 man) buffed - only tried it in a 10 man naxx - was struggling to break 3.2-3.5k TPS
2. Deep Frost: tried both with and without Guile of Gorefiend, with and without Tundra Stalker.
- highest threat of the above (2.) combinations was always a build that included both GoG and TS.
- highest avoidance spec of all due to Frigid Dreadplate, Unbreakable Armor and Lichborne
- very spiky threat, highly dependent of Killing Machine procs; unlucky streak and I am struggling to break 4k; lucky streak and 6k is usual (TPS).
- the very spiky nature of the spec makes it a bit less reliable when you have a 25 man's dps-ers to worry about; hopefully this changes with the next patch with a more reliable TPS output
- overall the spec is great to play with; feels nice, especially when you're on a KM spree
3. Deep Unholy (51p)
- this was the biggest surprise for me; I'm still trying to adapt to the play style; boy does this spec deliver...
- self buffed (HoW and BS) I was breaking 4.2k TPS easy
- managed to overagro MT (Warrior) on 25 man Malygos; standing on the dragon's side, not taking any sparks. Threat was breaking 8k per second
- the downside of this build is that it takes a while for the solid threat to build up; it builds slowly until all diseases, DnD and Unholy Blight are all up and running, but once they are there it's insane
- I only managed to try it on 25 man Malygos and 10 man Sartharion; we don't have a protection paladin and even without BoSanc, runic power was decent. If maintanking I would use Rune Strike, Deathcoil does the job just great if offtanking.
- I did not watch the numbers but I strongly believe it has the highest scaling potential in a raid. It benefits from both spell increasing buffs / debuffs, as well as melee ones. The damage range would usually be Melee, Death and Decay, Unhloy Blight with slight shifts between the latter and either Deathcoil or Rune Strike, depending if tanking or not.
- The spec feels very weird to play compared to every other spec I tried. Maybe due to it's "build-up" nature, it's not that ecstatic as others may be, up to a point. When you take a look at Omen.
This worked best with 26 expertise (capped dodge), capped (melee) special hits and max AP available on the gear I had. Also, Blood Boil seems to be following the above scaling logic, it hit for more than Blood Strike, at least given the raid setup I managed to run the spec in.
The sequence would start with laying DnD, then 1 rune of each on Plague Strike, Icy Touch and Blood Boil. This only produces 55 RP. Fortunately next patch Unholy Blight only costs 40 RP so that's great. For now, immediately after runes are blown up, either DC or RS as a power dump. Repeat with one of each of the above again, DnD finishes cooldown, then just alternate Unholy Blight and another power dump, aiming for 100% UB uptime. Normally, this means every other rotation. 15 Seconds and threat goes wild. I'm still experimenting with the build and playstyle, but so far it pleases me the most.
12/8/51 is the spec I run.
Butchery is nice for that extra RP generation needed to keep close to 100% uptime on Unholy Blight. Frost talents are a no brainer.
Naturally, more effective on tank and spank fights or less movement involving fights, due to Desecration. I'm no number cruncher, but i don't believe this has a make or break impact on the performance of this spec.
I feel Death Runes are counter productive for tanking, or at least for my play style. In each spec I tried one, it only messed up the rotation. The same for with Rime proc.
No scourge strike. Even if that deep in unholy, using scourge strike messes up everything in the above rotation, any time I tried a 2 rune strike made the DPS (when testing on dummy) / TPS lower. Anti Magic Zone was worth its talent point 5 times every time I dropped it.
Still, too little testing made so far, we'll go for a fresh Naxx clear tomorrow and I may have more observation after that. So far it's simply surprising.
My only regret so far is passing on all of the major 25 man upgrades in hopes of going for that juicy expertise gear advertised somewhere around the forums (here and / or tankspot). I saw no point in grabbing it from others when I was about to get proper ones for myself shortly. RNG failed me again, as far as expertise gear was concerned, the only drops being headpiece and neck.
Now that I've done all the tests I'd go for that set upgrades for the more avoidance, stamina and strength in a breath. That can only improve the Unholy spec more. Expertise seemed to have little to no effect over the dodge cap. (Never tested with less).
Guess the wall of text turned out to be pretty big. Unfortunately I have no idea how to measure all of the above from a threat standpoint. Point me to some tools, if any, and I can't wait to be able to also provide documented support for all of the above to be more than just words.
If you want to try something new, let yourselves surprised by this, I'm still wondering how it's possible. We're still far from saying the class has been known inside and out, aren't we?
