For people like me who saw these low numbers and assumed stats were all but useless for the most part, these numbers aren't exactly correct. Strength is incredibly good, because the +1 damage to attacks is added per swing. For example with the staff a basic attack chain would do 19>37>56. With one additional point in strength that damage increases to 20>3940>60. You're getting an additional 1 damage on the first hit, 23 damage on the second, and 4 on the last. That isn't the same for all weapons. For example, a mace and shield with an additional point in strength adds 1 damage on the first hit, 12 on the second, and 4 on the last.
