Mmm... let me see:

-They look totally badass in black amor with skulls.
-Death themed = cool
-Have pets = lulz that's awesome
-Have a lot of choices on playstyle (more than warriors at least)
-start at lvl 55 and have a free mount
-Arthazzz iz awesome lulz!!111!!!one!!

And you think people plays them just because they're OP?

By that logic, why would anyone play a priest, druid, shaman, mage, warlock, warrior, paladin, hunter, or rogue if they aren't OP?

A class should be played because the player enjoys that class more than the other 9, not because it's actually imbalanced to be mathematically better.

Or you know, not trying to shoot your down for being an ass or anything, but maybe alot of players have tired of playing the same 9 classes over the course of 4 and a half years? I mean, hell, if they had released SUPAH DRUID as the hero class I'd still roll it. I played a Warlock for four years. It was time to try something else. I had tried every other class in the game, and stuck to none; long nights spent pondering why concluded with one word: Dots.

And that would be the single reason I play a DK. Damage over time mixed with an entirely different play style. It's not that I said "OMG DK ROCK AND ARE OP." It's the same thing as when Warlocks were considered OP back in early/pre BC and a tremendous amount of people criticized me for playing a Warlock (though I always played Affliction...). I started playing a Warlock back in 1.3. Which you may not remember, it's been a while, Warlocks were laughed at universally. Low DPS, no survival, just a weak mage with a pet. They've finally been grounded to a decent level of high DPS/moderate survivability.
