I agree with everything Flux said, really. Maybe a one handed weapon mastery and a two-handed weapon mastery?
One addition would be no single-target, regular speed attacks. Even the most damaging (beserk) of single-target damage skills pale in comparison to say, zeal, or whirlwind, in damage, which is really pathetic and the opposite of how it should be, and D2 is about killing masses, right? I liked the "line of damage" and "small arc" of damage skills used in the movie.
