This isn't your blog. If you're going to start your post with "I'm too lazy to read but let me tell you why you are wrong" that's your clue not to post.
As I don't have the patience to work through 100 pages, I would add my 2 cents and would like to hear some input to it.
Before posting, this is my tanking spec and I do see room for alternative glyphs or 1-4 talent points for single/multi target threat switches, or even more survivability throug Glyph of Anti-Magic Shell, but overall it's the best way a blood DK can survive. Talent Calculator - World of Warcraft
I can't see why a Blood DK should spec like the opening post suggests. Death Rune Mastery and Scent of Blood are wasted points, as is Might of Mograine. You almost always have enough RP to constantly Rune Strike, and death coils don't do much dps/threat. The blood spec's weakest point is it's avoidance and absorbtion, but it's able to heal itself through various ways, primary death strike. A simple disease upkeeping rotation with focus on DS should be the main priority. You may get hit harder and more often than other tanks, but you always put in your own ~10k heals every few seconds, which are balancing this very good. And threat should never be the issue since the last IT buff. (One IT every ~20 seconds and 2 for every Blood Tab are more than enough.)
Rune Tap is another must-have talent. In combination with a Vampiric Blood you heal yourself for about 40 % of the life you got without VB and combine that with a battlemaster trinket or something like Blessing of the Naaru and you got a very mighty cooldown combination.
And yup, Blood Worms DO heal. They heal for 250-400 per hit, and they are many. It's an effective health buff which can keep you alive, you only could spec into more threat, which is absolutely not relevant. On many fights they even absorb many nasty debuffs, spells and hits from the bosses, which otherwhise would hit your fellow comrades or yourself.
Without selfheal there is only one possible excuse to spec into blood as a tanking DK: WotN. And I can't accept that a single survival talent (although almost OP for itself since the buff) can justify the loss of a very big bunch of absorbtion, threat or anti-magic tools, you would get with Frost or Unholy.
Also I would like to support the "Glyph of Horn of Winter - Haters Club" with this post! Glyph of Blood Tap should be mandatory.
If my statement was already posted somewhere below, I humbly apologize for your stolen time. If not I was pleased to add my ideas, although they are working very much for me in practice.
