Damage?

Only Duel Guns' maximum damage is boosted and not minimum? Kinda throws the min-max difference though the roof. Plus, do they benefit from Combat Mastery and/or Ranged Attack as far as additional damage/balance?

Quite sure we're just missing the minimum damage formula, not that it doesn't exist.

And I would assume they don't benefit from ranged or combat mastery, considering they're not ranged or combat skills (in the sense of skill type, not categorization).
