I'd love to see multi-hits make a difference (though that would probably require the likes of a Stagger or Armor [Penetration] undermechanic), and for the player be able to choose from among, say...
  • Show each hit, fading slowly, with a separate cumulative sum
  • Fade each hit into the cumulative sum
  • Fade each hit without cumulative sum
  • Show only the cumulative sum (one number per action)
