Heh. Oddly enough, I do the opposite. I dislike not rolling for my NPCs, so I always subtract 6 from their scores and roll a die for the NPCs instead.

But I do go ahead and pre-figure out the bonus. So, if my cultist NPC has a Dexterity of 3 and a Hand Weapon: Knife of 2, I write it on their manuevers as Knife: 5+d10

My PCs also really dislike not rolling for damage, so we've imported that back to Cinematic from Classic.
