Hmm.
Does it do anything to fix the combat?
In old Vampire a character with Dex 3 and Melee 4 rolls seven dice. Gets four successes. The opponent rolls dodge, gets one success, leaving three attack successes. The attacker adds Strength 3 and Potence 2 to the weapon's score of 3 and the 2 extra successes. The attacker rolls ten dice, for four successes. The defender rolls Stamina 2, Fortitude 1 and Armor 1, for two successes. So the defender takes two damage.
That's four rolls. Not exactly elegant.
