DK's were pretty fun, got one to 71st. was just fun seeing the new abilities u trained after lvling up, and feeling stupidly OP after playing the normal classes. But thats WotlK, everythings too big, scary and powerful (from a pvp point of view) what little gameplay and skill that was needed just faded away, and its now a race to spam the big dmg button b4 the other guy kills u. I even started raiding, yes thats how bad the pvp was. But after the novelty ran out (v. quickly) that got boring and repetative too. So, thats why i stopped playing, and won't be going back, barring a major re-haul of the way pvp works.
