Vampiric Blood boosts health/healing, and as such requires coordination from a healer to be of any real use, making it a crappy defensive CD. Death Strike's healing can potentially be significant, but even so its not a true defensive CD in the original sense of the term (plus the blood shield it provides now is atrocious). Blood Mirror is slightly better (20% damage redirected for 10 seconds), but requires me to spec into it instead of Purgatory. I usually do anyways because I have no real defensive otherwise. Of course I could spec into Rune Tap and consume a rune for 25% reduction for 3 seconds. A rune I might otherwise need to maintain my Bone Shield or use to generate RP so I can get a Death Strike off so I don't get fucked by an ability that REQUIRES active mitigation to survive. Because apparently despite being the class that INVENTED active mitigation as a tank utility, we have jack shit for it now. Mind you no other class I know of has their strongest damage reduction cd require their class's base resource to use.
Frost and Unholy also do not have three defensive CDs either. As frost I have Icebound Fortitude for 20% damage reduction and Anti-Magic Shell to nullify up to ~30% of my health in magic damage. Neither of those are very good as defensive CDs, plus IBF has a 3 minute CD (compare to a shaman's Astral Shift with 40% reduction every 1.5 minutes). To my knowledge unholy doesn't get anything else beyond those two either (though I could be mistaken).
