I think one of the high points will be/is that rime procs from both hands when you Obliterate (at least as of today), so you can get more HB's in. Which is a pretty awesome.

Hey, thanks for posting it. However, is it possible to include a parry rating inside there?
This is because when I last checked, parry resets swing timer, allowing for more tps.
Maybe the other mitigation skills also, for more RS procs. Just an idea to see if it's possible.
Also, am I right to say expertise cap for dodge is 28? Thanks!

I see in the original post that the Frost spec has 1 point in Hungering Cold as opposed to Deathchill. Hungering cold is very situational in its use whereas Deathchill would be very helpful in getting snap aggro. I understand Hungering Cold infects your targets with Frost Fever, but then again, if you are glyphed for Howling Blast (even if you are not), the Deathchill + Howling Blast (or Frost Strike) is practically a KM proc on demand. Very worthwhile to change as people may not read into the importance of Deathchill and go with Hungering Cold, which they will very rarely use.

I use Hungering Cold for fights like Faction Champs where I run in and provide the opener by freezing every champion. Then the other person who would originally open (maybe a warrior with aoe fear) takes over. Other than situations like those, Deathchill is great -> think opening with Deathchill/HB on Gormok to give your DPS less downtime in the beginning.

The common assertion that two fast tank weapons do significantly less damage with strikes is a myth. Remember that tank DKs have very high relative AP due to bladed armor, and DW scales better with AP than 2H does.

One-handers are AP normalized to 2.5 speed while two-handers are AP normalized to 3.3 speed. With 5000 AP, the base damage of Obliterate (before talents, glyphs, armor) on a 3.6 speed 245 two-handed weapon is (255.6 * 3.6) + (5000 / 14 * 3.3) = 2098.5. The base damage of DW Obliterate (no glyphs, no armor, only talents are ToT and NoCS) with two 1.6 speed 245 weapons is (191.7 * 1.6) + (5000 / 14 * 2.5) + 0.65((191.7 * 1.6) + (5000 / 14 * 2.5)) = 1992.45. That's all of 5% less. If you have 6000 AP, the DW Obliterate actually does more damage than the 2H Obliterate.

Now, I just used Obliterate as an example, but all strikes are calculated the same way. They just get a damage multiplier at the end. Blood Strike does 50% damage, Frost Strike does 55% damage, etc. Because of this, the damage difference between any 2H strike and DW strike with 5000 AP is still going to be 5%. Since talents and glyphs mostly just add %damage modifiers and %crit, they're not going to affect that 5% difference. AFAIK, every talent that does affect 2H and DW unequally favors DW.

When you consider all the other advantages of DW, such as higher white damage, lots more RP generation from Scent of Blood, double Rime procs, etc., I would be very surprised if DWing 1.6 weapons didn't beat a 3.6 2H in threat. You only have to overcome a 5% damage difference from strikes only!

The main issue with DW tanking right now are that WotN + VB are generally better tanking talents than UBA + Frigid Dreadplate. But if you have the right gear for DW, I'd suggest DW all the way. FYI: The procs on Gleaming QS and Burnished QS stack. This is incredible for tanking if you can get them both to drop.
