That is true. I think arrows would be best left as a laser, like they are now, but as part of the unique factor of them, add a way to increase range with that increase in firing angle, maybe have bow be less damaging, but more accurate with a higher fire rate. Crossbows do the most damage, with the best penetration, but have a low firing rate, and lowest acuracy, guns have medium accuracy (no modifiers), medium damage (no modifiers), the fire rate would have to be figured out, but I think full attacks should be possible, only having restricted ones to crossbows. Theses stats would be assuming access to feats/PrCs/etc. that benefit specific weapon groups, so the fire rate/accuracy/range of the bow would be because of a feat, or a PrC, otherwise they would be very similar to a gun.
That seem reasonable?
