i'd like to see a crossbow as an extra weapon type. not a replacement of the slingbow, but an addition that uses bolts (not arrows as those are different). basically a return to the old slingbow that was not AOE only, but allows for both parties to have a Area Of Effect Slingbow, and a not AOE crossbow. Or just bring back regular marbles as an option. either way works.
For a culture that has figured out the crossbow, the bow is actually a step backward even though it was discovered first.
The reason is, it is harder to learn how to properly use a bow at long distances whereas crossbows are "direct fire" weapons. It is easier to train people how to use a crossbow even though a bow was superior in performance. Also, holding a bow at full draw to aim actually requires a lot of arm strength.
Therefore although we have the slingbow, regular crossbow bolts should be alternate ammunition.
