Reason:
It might be just me, but crafting ammunition is a total pain in the arse. You need to buy or scavenge for materials fairly frequently on top of the hassling with the templates. This can feel like busywork to those who don't care much for the crafting system.
Solution 1
Introduce a few inferior bows with unlimited ammunition to the archer store in Myon for AAs only and to a similar store for drow. These would be a clearly inferior alternative to the template-dipped arrows, but people could avail them without hassle for easy content to spare their more precious ammo. I also think the unlimited arrow weapons are thematically nice for arcane archers, though I understand opinions to the contrary.
Solution 2
Add a very easy craft template for iron arrow bundles or a tasteful alternative to the crafting system that is only craftable by AAs. This way the AAs arrows would still be 2 damage inferior to damask, so there would still be an advantage in buying arrows for others or crafting the damask yourself.
As an example of the AA's own "iron arrow" bundle:
Solution 3Arcane arrow
DC x, craft points x
Materials: arrow shafts, magic weapon scroll
Product: Arcane arrow bundle (+1 damage)
Give arcane archers the "conjure arrows" ability to conjure a bundle of "magic arrows" per day with fixed, untemplatable stats inferior to what a template would produce.
Solution 4
Give arcane archers the same feat as archer-pathed Rangers have to craft their own bronze or iron arrow bundles for free.
Problems with the suggestion
The problem isn't really a problem and it's all in my head and would therefore be a waste of development resources.
Sorry for the lack of specifics in the solutions and thanks for your consideration.
