1)You have to monitor a pet, which some people just don't like.

There's no "petless" unholy, and some people just don't like managing pets.
2)It has a long ramp up time to really get going. That can be okay in boss situations, but if you use the same spec to say, run your dailies as well, it's not as efficient as frost OR blood-it doesn't have the burst and aoe frost has to kill lone mobs or small groups, and it doesn't have the near invincibility that lets blood take on 15+ mobs at once without concern.
