Aight, so last post I talked about the wonky math in OneDice Fantasy. I looked over Cyberpunk as well. The problem isn't quite as pronounced because there are no fantasy races that give you a free 3 or 4 in an ability. The highest Defense, sans armor, that you can achieve is 9. Now, this is still rough on a character who starts with Clever 3 and Shooting 2, who still has to get a 5 or 6 on his target. (And that ignores factors like armor, cover, etc.)
Normally I don't like mechanics that let you "dodge" modern firearms. I suppose it's appropriate enough in some Cyberpunk genres that we can let it slide, though I like the idea of seeking cover in crumbling alleys and behind cars during a CB shootout. So, my proposal:
Melee Combat: Defense = Quick + Skill.
Ranged Combat: Defense = Quick. A character with some kind of cybernetic enhancement can add Acrobatics or perhaps double their Quick. Better armor up and take cover, chombatta.*
I imagine I'll have slight variants for Steampunk and Urban Fantasy, especially because the latter game seems to stress supernatural toughness as factoring into a character's Defense.
*Ah, Cyberpunk 2020.
