The standard tanking spec prior to the most recent talent changes was frost/blood, generally to frost aura, and (blade barrier a few patches ago, but recently...) veteran of the third war for blood, as far as I'm aware.
The way I see it, these are the real tanky-like talents we have so far-
(*=Spell mitigation talent)
Blood
Blade Barrier
Spell Deflection*
Abomination Strength (not really but people would cry if I didnt list it)
Will of the Necropolis
Frost
Toughness
Lichborne
Frigid Deathplate
Unbreakable Armor
Acclimation*
Unholy
Anticipation
Unholy Command
Magic Suppression*
Bone Shield
Being that Frost Aura, the main reason I was planning on going down frost so far, is Extra useless for tanking now, I see no reason to go down further than Frigid Deathplate.
Blood, with Blade Barrier being a first tier talent, is worthy of about 5 points (or 10 if you dig Bladed Armor, which I do). Yes, Dark Conviction is nice, but not if you want Frigid Deathplate And Bone Shield.
Unholy, which I formerly had no intention of going very far into for tanking, is looking much more appealing with the death of Frost Aura, and also the change to Unbreakable Armor. Bone Shield will be up more often than Unbreakable Armor, (and potentially mitigating more damage as well), in addition to Magic Suppression which imo is the best spell mitigation talent DKs have, and I believe these to be worth the swap to unholy.
With the current build I'm looking at something along the lines of this now:

What do all of you future DK tanks think of the changes/plan on doing?
