So back to the main question, is it worth the development time to add these? Is there any significant advantage to adding these, even for fletching? I am asking this question on a community level - not just directly to you. And you've twisted my words a bit, i did not say they were relatively low XP yield, i said there is little to no XP advantage (implying over current methods).
As mentioned, I'm looking for community response. Not just you yourself - is there a benefit to these overall, etc?
