It's the simple things in life LOL. took a break from lvling the Druid, jumped on the DK (Unholy) did the invasion at ilvl 821 and oh my god... I just shred through mobs like they're nothing... It's great fun. I can only imagine how strong this will be in 900+ gear. Casually tagging every mob in sight, getting them close -> FW/Defile etc scourge strike cleave and everything just dies... so much more enjoyable than my Druid, Rogue, Pally, any other class I play at the moment. Obviously not forgetting Frost is pretty incredible with Frostscythe KM procs.... I remember that before unholy became the better spec and it was just ridiculous...
Unholy - very nice.
