I wish I could feel confident playing a tank. All the years I have played MMOs I never played a tank role. It may have something to do with how I grew up though. Playing army with my older brother and his friends they would only let me be the nurse being a female back then women were not in combat roles so I always was a healer. Fast forward to MMOs I just never tried it and always thought I would be bad at it. I admire people who are tanks for the control they maintain over a boss or dungeon though.
