I've been having a hard time deciding between dual wield and 2h for my barbarian. I've tried both and read a bit on these forums; seems to me that 2h is better when facing high DR opponents but dual wield is more effective against enemies with less DR. Basically I'm wondering if it is equally viable to get both weapon styles and switch weapons according to the situation, or to just get dual wield and vulnerable attack to deal with high DR. Does anyone have any thoughts as to which would be more effective, or if they are comparable?
