I tried leveling both tanks a bit before HW, i didn't have much play time due to work and such so i never got to experience the full potential of either class, but from what i have seen the Warrior was definitely a great time. I decided i wanted to try tanking full time in HW since i will actually have time to play it this time, so i picked up the DRK. It has been a pretty fun time so far, tanked all of the dungeons up to 50 with little problem. Ill push it to 60 and see how it goes but so far im really liking DRK the most.
