Actually, it is very useful. No it does not help with enhancing, but as others have said, it is very useful when using runic kits. I am sorry, but i am not going to waste one of the 15 charges on a barbed runic just to get a non-exceptional leather tunic. And it also saves quite a bit in bones when filling up exceptional lbods. It adds up. As far as the costs of getting there, +20 tailor scrolls are really quite common. If you do BODs, you should have no trouble getting them. If you don't do BODs they are not very expensive at all. I have a hard time selling them for 400k on Baja. To get to 120, many people, myself included, used about 60k leather to get to 115 and the aos gift to skip the bones. I think I have actually saved money by going to 120, because i can fill out BODs easier.
