I see a number of people making their classes into Duel-Spec..I was just curious about What is the best Duel-Spec to have to benefit you from boss killing and will not die during rushes and Killing the bosses or just a good class to farm money that can solo and team

I would like to know specfic detailed information on the gear and attribute points. The gears to bump up the atrributes Str, Dex or Int. Also the skills or combos

Hope you answer my question
