I'm not sure I like any of the tank jobs currently. Dark Knight has a lot of weird design choices that make me question how much thought was put into it, Paladin is still the typical sword and board 'tanky' tank (snooze mode), and Warrior getting a dps stance and encouraging role segregation for jobs is pretty up there on the 'meh' scale.
I do, however, like tanking so it's whatever I have to play to get the job done for best performance in group.
