I suppose I'll chime in here, since I have been an unholy tank for a long time.

While it's true that unholy has lower single-target threat, I've never had a problem with dps pulling off me. Lower single-target threat does not mean that unholy tanking is non-viable: if you out-threat the dps, then there is no difference between out-threating them by 500 or 5000 TPS, because the result is the same (you hold agro on the boss).

I've also had very few survival issues where I wish I was a Blood tank, although this might change once we start into the ICC hard modes. Bone shield's passive 20% damage reduction is stellar for OTing, and is effective for known incoming big-hit damage reduction. The passive 6% magic damage reduction from Magic Suppression is also nice, and my AMZ can absorb 18k damage before popping. Considering the amount of magic damage flying around in ICC, I've found all my unholy survival 'buttons' to be useful. I haven't yet been in a situation where the extra 1k health from being blood would have been make or break, or where WotN would have saved the raid.

Finally, my DnD hits hard enough that I never have to worry about aoe threat, which is an area that I gather blood tanks do occasionally have to worry about.

Of course, EP is the real reason to be an unholy tank, even for me, because it means that we don't have to worry if there's another unholy DK in the raid or not.

At this point in my game, being any spec of tank would ultimately be a matter of personal preference and play-style, and not a matter of survival or threat.

There's a huge difference between the two. Strength converts to attack power and attack power is what increases your damage done. Haste is a completely different stat and its value depends on your other stats. Dumbed down, you can think of stats as getting better the more of other stats you have. A very much simplified example is crit chance and attack power. For an attack power that makes your white hits do 5000 damage, an extra 1% crit would increase your damage by 50 (51.5 with CSD). If your attack power made your swings hit for 6000, 1% crit would give you 60 (61.8 with CSD).

This is why equivalence points and similar scales are given for certain gearsets and aren't entirely accurate even then. The best way to find such a scale would be to load up rawr with your gear and use the number it provides, but as its warning says, those numbers are only valid for the gear you have on at the moment, changing it will affect the relative values of stats.

Belt Question.... Why was the Coldwraith Links belt replaced by the Vengeful Noose??

This question has already been answered several times before on the previous pages. I suggest you read that, and you'll surely find your answer.

Ahhah, aye i've been poking arround a bit, seems the only way to get a larger heal is more HP *Shrug*
However, this brings me onto another point. Not sure if it's already been coverred, but itemization for ICC?
Seeing with the 20% drop in dodge, are we going to try and make that up or ignore it and invest elsewhere?
As far as I am aware, Blizzard implemented the dodge nerf due to tanks taking far to little damage, they then tried to increase boss damage so when they did hit it was substantial, but then yhe problem came with diminishing returns and tanks would get "1 shot" - Like in ToC 25 heroic, we had this problem on Gormok in particular.
Seeing as alot of the ICC gear has bonus armour on it, I'm wanderring if we should start gearing arround soaking damage than avoiding it.
I also see a large drop in the ammount of block on ICC gear, which puts our parry as our highest avoidance stat *Cringe*
I've also taken a disslike to the set bonuses, the 2 set is great threat, the 4 set however doesn;t seem to have a logn enough duration to catch my interest, I can only see it stacking up your diminishing returns on dodge, then dropping you in the deep end - that and it only lasts for about 4 swings. the general loss in stats for taking the tier set over the 251/264 ICC gear and emblem rewards seems to much to bother with.
Am I just being silly? How are you gearing at the moment?

I have a death knight but rarely find myself playing him nowadays. I liked the class alot, and would happily consider it my main; I just couldn't tank correctly. I tried everything imaginable but I couldn't find a way to get guys to stick to me. My major problem was aoe, but really, it's all traced back to the rune system IMHO. Paladins don't have to worry about their Consecrates taking up half their mana pool, but Death and Decay used 1 of each rune. Once it's down, I can use my last 3 runes on IT/PS/Pest or HB/BB. The entire rotation, including the initial DnD, takes a good 5-6 heart-pounding seconds in my experience. By the time it's all out, someone (and hopefully only one person if I'm lucky) has already pulled from me, so unless I have rune strike up, I'm properly fucked for the next 10 seconds until my runes are back up. Dark Command would work, but taunts shouldn't really be such a fundamental part of your rotation IMO. Aside from that, once everyone's pulling from my piss poor AoE Threat, the whole mob is so clusterfucky and all over the place it gets incredibly hard to manage.

So the way I look at it, as a DK tank, I get hardly 4 or 5 attacks every 10 seconds, whereas Warriors and Paladins and even Druids really have exceptional snap aggro and cleaves. Has anyone every encountered a problem with this kind of limitation? I'm hoping that I can stack haste in cata, and hopefully find this class actually useful as a tank!

My recommendation about the keybinding stuff, buy this: N52TE



sidenote: you can remove the joystick-ish poke to turn that part into a arrowpad like that of an oldskool console controller if ye don't like the poke.

Use that part to walk so only 1 finger (your thumb) will be busy at most with moving, leaving 4 fingers left to focus on the 14 other buttons.

No more keybinding nightmares. Took me 2 days and then i was fully used to walking with only my thumb.

As for my own UI:

If you're looking for snap aggro you might want to dig into the frost tree. I take it you're talking about trash or packs of mobs? Howling blast (glyphed if perferred) is great for that.

If you check SimulationCraft thread, you'll see CoA is just about 4.9% of affliction warlock's dps. So even if you are the only caster dps in your raid/party, you should use CoE.
