Also if you dont let players use their BS for shooting, you could let them assist. Eg one player tests BS to add +10 to roll.
As for the skills, it is reasonable to add a bonus to crew rating when testing skills. Crack crew (40) should have skills at +10, unless crack means that they have 30 +10. Also veteran and elite crews should have skills at +20.
Yeah, that was how I did it. I assumed someone on the NPC ship (or, more likely, several someones) was actually competent and using lock on target, put your backs into it, have a +10 because I'm a RT, etcetera. I gave the NPC ships a flat bonus (usually +20 for run of the mill foes) that could be divided up amongst their rolls. It seemed to work reasonably well.
