Hey so I've been playing a barbarian as a dps class for the most part so far. Having just completed Nightmare mode I was wondering how crucial a tank is needed for Hell mode. I know I'll be needing to go tank at some point, especially if I'm playing with other people, its just a question of when. So will I still be able to play as a dps'er for Hell mode and just swap to tank for Inferno, or should I be making the transition already.
