To illustrate my point, let's look at a rotation with Blood of the North...
For the sake of simplicity, I'm going to ignore Death & Decay here, since it really throws a monkeywrench in the whole process. I'm also going to keep out runic ability, since they're largely irrelevant in this context.
Step 1
0.0 1 Frost; Icy Touch (20 second Frost fever)
1.5 1 Unholy; Plague Strike (20 second Blood plague)
3.0 1 Unholy/1 Frost; Obliterate/Death Strike
4.5 1 Blood; Blood Strike
6.0 1 Blood; Blood Strike
- Proc Blade Barrier.
Now that we got the ball rolling,
Step 2
10.0 Frost Rune Refresh.
11.5 Unholy Refresh. 1 Unholy/1 Frost; Obliterate/Death Strike
13.0 Unholy/Frost Refresh, 1 Unholy/1 Frost; Obliterate/Death Strike
14.0 Blood Barrier fades
14.5 Blood Refresh into Death; 1 Death; Icy Touch (refresh Frost Fever)
16.0 Blood Refresh into Death; 1 Death; Plauge Strike (refresh Blood Plague)
- Proc Blade Barrier.
Step 3
21.5 Unholy/Frost Refresh, 1 Unholy/1 Frost; Obliterate/Death Strike
23.0 Unholy/Frost Refresh, 1 Unholy/1 Frost; Obliterate/Death Strike
24.0 Blood Barrier fades
24.5 1 Blood refresh; Blood Strike
26.0 1 Blood refresh; Blood Strike
- Proc Blade Barrier.
Step 4
Repeat Step 2 and Step 3, rinse and repeat.
As you can see, you get to keep Frost Fever/Blood Plague up at all time. You get to do 2 double disease obliterate/death striker per set of cooldown. And you only have a 2 second downtime on Blade Barrier.
Now, without Blood of the North...
Step 1
0.0 1 Frost; Icy Touch (20 second Frost fever)
1.5 1 Unholy; Plague Strike (20 second Blood plague)
3.0 1 Unholy/1 Frost; Obliterate/Death Strike
4.5 1 Blood; Blood Strike
6.0 1 Blood; Blood Strike
- Proc Blade Barrier.
Step 2
10.0 Frost Rune Refresh.
11.5 Unholy Refresh. 1 Unholy/1 Frost; Obliterate/Death Strike
13.0 Unholy/Frost Refresh, 1 Unholy/1 Frost; Obliterate/Death Strike
14.0 Blood Barrier fades
14.5 Blood Refresh; 1 Blood; Blood Strike
16.0 Blood Refresh; 1 Blood; Blood Strike
- Proc Blade Barrier.
Step 3
20.0 Frost Fever Fades
21.5 Blood Plague Fades; Unholy/Frost Refresh; 1 Frost, Icy Touch (refresh Frost Fever)
23.0 Unholy/Frost Refresh; 1 Unholy, Plague Strike (refresh Blood Plauge)
24.0 Blade Barrier Fades
24.5 1 Blood refresh; 1 Unholy/1 Frost; Obliterate/Death Strike
26.0 1 Blood refresh; 1 Blood; Blood Strike
27.5 1 Blood; Blood Strike
-Proc Blade Barrier
I'm going to stop here, but suffice to say it gets messy. And it only get uglier if you throw in Death & Decay in there...
You have more blade barrier downtime (3.5 sec instead of 2), you lose out on 1 Obliterate per rotation and you're going to have a hard time keeping both disease up at all time. You spend the whole fight playing catch up with your timers and any little mistake you make is going to make you suffer... while the Blood of the North DK has a really smooth rotation that essentially take care of itself.
And ultimately, the lost of Obliterate/DS will also lower your dps/survability in solo pve as well, meaning you're actually WORSE at solo if you don't take it.
So yeah, Blood of the North is a pretty big deal if you want to use Oblit/DS... Now this doesn't necessarily mean much, it's quite possible that Blood Strike will end up being a 'better' threat builder overall then Death/Obliterate so that Blood of the North won't be good for tanking... but I honestly highly doubt that.

Hypothetical question here. Frost Strike is more damage than Death Coil, but is it that much better for tanking that it's worth the talent point? I'm just trying to imagine a scenario where speccing to tank with a DK might eventually look like speccing to tank with a Paladin, where every last point is crucial and not like a Warrior or Druid tank build, where they have points to play with.
Well, it is only 1 point and considering you'll want to go pretty deep in the Frost Tree as a tank, it's most likely not going to be a big deal to pick it up.
Remember that for every rotation up there (in my examples), they would have been a RP dump near the end... so you actually get to use Frost Strike/Death Coil about 6 time per minute, upgrading from DC to FS thus is a pretty big deal.
Frost Strike does more damage because it's based off weapon damage, it has a +X component and lastly, it synergise with killing machine and death chill.
Once again, it's hard to say without any level 80 DK running level 80 content as tanks... but considering that the DK's threat come from damage, this seems like a pretty obvious choice.
