I just started playing on my dk again, as frost and unholy dps. But I don't like those speccs. I really really miss the Wotlk blood dps!
Blood was a unique dps specialisation with very cool mechanics wich I really liked. Heart strike was really awesome and bursting with Dancing Rune Weapon was so cool. Frost is so boring and braindead while Unholy is clunky and extremely rng-based. Why did they remove blood dps? Sure we needed a dedicated tanking tree but I honestly think that if there has to be one tanking tree, it would have to be Frost.
Yes, Frost. It makes the most sense: the Death Knight protects himself with ice, frigid deathplate etc. made sense. While Blood makes the Death Knight able to control the blood of his foes making him a real damage dealer, not a tank.
Who shares my opinion? Who likes to explain with decent arguments why Blizzard decided to make blood a tank tree and let frost be dps tree?
