I made this more as an example of a lesser-known DK play style(DW Unholy 0/17/54). The build tends to produce pretty comparable DPS to 2 Handed Unholy on most fights, and in a lot of cases I surpass equally geared Blood, Frost and Unholy DK's under equal conditions.
This is a non-slagged Ignis parse, which made it a pretty good candidate for maximum single target DPS test, in this case the parse ended up in the 6400DPS range, with a total of 1514 damage done to Iron constructs in the process.
Its a single rune priority rotation, you never use Obliterate, or even have any other double rune abilities such as Scourge Strike. The spec plays very fast, and very fluid once you understand it.
The video isn't the best editing but it should be watchable and hopefully a few of you enjoy it, its decent enough for a view if you are interested in how the build plays in a raid environment.
