I am a triple boxer and so far love my DK team. They are 74 and I'm sure that they will all be unholy spec when I hit 80, lots of fun and death grip gets the ranged action close. One thing to note though is that I do have a N52 mapped with the thumb stick to control my secondary toons WASD if the hit box is too small. But you should already be ready for that with targeting vendors and questgivers. If I had the time to level the pallies I would say those are fun too, I have a 2xpally 1xsham team and they are a blast to run.
