So Here are the suggestion as clean as possible as a list.
1.Simple bow requires plant fiber rope insted of plant fiber.
2.Add first tier arrows crafted as a bowcrafter to be wooden arrows maybe even next tier ones those that require flint.
-A wooden arrow would do minimum damage thus nerfing early bow users significantly, a stone one can do slightly better dmg for the sole reason because it requires another material apart from just a billet as the wooden one.
3. A blacksmith can make arrow heads of different kinds in bundles of 10(similar to nails) because 1 band is 10 arrows currently.
- Different arrow heads made out of metal bands or bars or what ever seems logicaly fiting.
-Pros adds more diversity and realisam with not alot of new work just different items.
-Arrow types can be the same as in game or even new ones later on cosmeticly different and so on.
4.A bowcrafter uses billets to make wooden arrows that can be combined with arrow heads of different types to get arrows with metal tips out of it.
5. Also adding a fleathcer shop would be nice it did exist.
