Well the patch has some good and some bad in it for DK's. Mostly good. On particular note for the original question but the second spec you gave I would recommend to you the following.

I'm not sure if this was a mistake or something you missed but not taking 3/3 in ebon plaguebringer is just wrong. Now it seems you are running four shaman but if you have a druid in there for earth and moon then I stand corrected. But otherwise passing up 3% extra crit for you, extra disease damage for you and 13% more magic damage for you and your four shaman for a measly 2 more talent points?

Anti-magic zone got nerfed this patch because it is hella useful. A ton of dungeon bosses are throwing out all sorts of AoE damage or direct spell damage to off targets and that shield sucks down a good portion of it. Now you CAN just eat eck's spit (hopefully just the tank but you know how it goes sometime), or ionar's spiders, or loken's aoe, or the snakey boss's poison nova, or the collossas ground puddles, or the princes ice tombs, or his shadowbolts, or the constroctor's magic, or anything that is not physical damage that comes from a billion other bosses. But why should you eat it when you can just pop a bubble around your group and have it suck down 75% dmg reduction for you. Even if an AoE blows it to pieces in one shot for that blast you take 75% less damage. For one talent point. The prereq is also awesome for the points. 5% less damage on anything not physical is a very nice reduction in damage and a must have for any unholy tank imo. Now that I'm more comfortable in heroics and have had time to experiment with AMZ in my runs I have found tons of uses for it. It got a HUGE nerf because it is hugely awesome. One talent point for a group wide 75% damage reduction with a cooldown that allows it at least once in every fight.. yes please.

Wandering plauge, even with high crit levels, is not a spectacular talent. It just does not crank out the dps and threat that you would gut feeling assume. Paper math and WWS parses confirm this and so many choose to skip it for more interesting things. But on the theory that any AoE damage is good AoE damage especially non-global cooldown damage then go for it. I personally find my AoE threat to be quite through the roof personally so I choose to spend elsewhere but I won't knock you too bad for liking this talent.

The gargoyle is getting a pretty huge nerf. He was a pretty nice wallop of DPS so they decided to clip his wings a bit. Now for a "tank" a lot of people skip this talent because it was independant DPS and therefore did not count towards threat generation. Why burn your runic power on something that is not pushing you further up in threat letting your DPS, if they somehow were throttled, to open up more. But my threat was always way out in front with my group and guild groups I've run so I had him specced just for dps purposes. Will reevaluate after the nerf if my runic power and talent points are better spent elsewhere.

Unholy Aura is a nice talent. Now for heroic dungeons and the clunky aspect of repositioning a boxxed group mid fight in addition to the fact that I choose to mostly just eat or AMZ anything that would cause me to move means the dps increase aspect tied to run speed is greatly reduced and probably pushed close to, if not all the way to, zero. But 15% run speed is 15% run speed and it does add up. It IS noticable even if not spectacuraly noticable that a 100% mount would give you. The truth is you are moving from point A to B more often then you think. Not just in dungeons but within keeps, tunnels, multiconnected shops/etc. in cities. Although not ground breaking and providing little extra ability in the manner of multibox killing of things I find it's worth the 2pts. Your mileage may vary.

What I'm probably going to spec into today : Unholy Tank

Dirge chosen over butchery because you get more Runic Power back when you need it most (in the fight). With my cheesy rotation you get 20 extra runic power every 20 seconds.. better rotations would generate even more. Your mileage and playstyle may vary but I like dirge here since I like having the steady stream during boss fights as opposed to bursts of power as a pack dies due to aoe.

Some people have reported how awesome rune tap is with the glyph and i wanted to try it out. One blood rune for an instant 1500-2400ish hp heal to the party could be a bit useful for one point. but it is a flexi point for me.

The point in gargoyle along with the point in rune tap might both move into morbidity if I find I need to use it more. Or find I should be using it more. Again your mileage may vary.
