Snapping necks means disposing of bodies, though, and is a good way to get the heavy squads sent out after you. And I'm pretty sure banging two dudes' heads together means I have to find the grappling rules, bane of RPGs since the dawn of time.
As for the Bow/arrow damage...I like that reading, but I don't know if it's right. A Rating 8 bow would just need Rating 10 arrows to do max damage, so even more money/shot.
Maybe this is all intentional, and the designers actually wanted bows to exist, but be a clearly inferior/more complicated option than just bullets? It'd fit with the stylistic tone of the cyberpunk genre, since bows are decidedly non-futuristic and non-punk, but I wish it was clear if that was their plan. Not that DV14 anti-tank rifle arrows were actually better...at least in 3E you could have a 'bow' firing arrows made from rebar, which while very silly could probably punch through armor.
