As i figured.. shows when the fletching recipes actually changed from classic/kunark/vel/luclin to pop
and that shows when you could make those crazy bows and shit.

Well.. if you click on the classic tab , kunark, or velious tab you can make cultural arrows in those eras.
Anyways if i find anything else ill be sure to post it here. I expect tribute from all rangers when/if this ever gets put to work.
