After discovering that the boss target dummy in orgrimmar has no armor (some boss he is!), I decided to head to dalaran after the servers became stable again and do another test, using a supposedly higher dps build of http://talent.mmo-champion.com/?deathknight=2305320530000305201150213510000000000000000000000000000230200305003100000000000000000
The results of this higher DPS build on a target dummy with armor?
As you can see, this is substantially lower (and rightfully so, since this target has armor).
Notice the overall make up of damage. It's mostly necrosis + white damage. What does this tell you? Kiss 2hand viability good bye, unless things change considerably for the better with regards to 2h scaling.
Overall, I'm simply underwhelmed with the damage I am putting out right now.
