I love the way if you are a blood DK you are assumed to be a tank. Yet a prot warrior is not considered as much. I rarely FC with my blood DK. I like to duel in blood. I can kill you as quick as most classes. Rogues can drag a duel out longer than any class yet I don't see ppl refusing to duel them. Frost is not really a good spec for dueling. Too easy to kite. Most ppl don't like blood because they don't like having a challenging duel. Mainly though I enjoy beating OP classes that usually own DK's, and watching them cry.
Allow me to explain. As a DK you're a dps or tank. If you go blood, you're a tank. Just because you don't FC doesn't make you anything but a tank. Blood does less damage and survives longer than other specs. You are a tank.
Regardless of whether or not you're a tank, it's still one of the most faceroll specs in existence, if not THE worst. A duel with a blood DK isn't challenging, it's a tedious battle that never ends assuming equal gear. And a duel AS a blood dk? As I said, one could achieve the same success by mapping death strike to the majority of his keys and slapping his genitals on the numpad. If the player is a woman, god help her for she cannot play blood.
Really, go test your DPS against an unholy DK. Then health and survivability. And let me tell you, blood DKs are not meant to be killed by a single DPS. That's why they carry flags. There is no honor beating somebody in a duel as blood. The class is literally DESIGNED to sustain high amounts of damage while putting out low-moderate damage at the same time.
Sorry for the long-!@# rage post. I just had to set that straight.
