I hated DKs until I actually made one. Leveling a resto shammy during the expansion pack, I tried healing ramps one fine day with 4 DKs. Each one wanted to death grip their own mob.
I named mine Craptastic as a joke because that's what I thought of them...and then I started facerolling people.
I recently learned herbing and maxed it in about 5 hours. I then leveled from 83 to 84 by only herbing and mining.
Didn't get much new gear but I make 4000 gold selling mats and gems!
