Maybe old topic here but just now getting into this myself.
For those of use trying to craft ascended armor silk price is a pain, but the real kick in the family jewels has been wool, cotton, and linen. Why are prices so high? Well, quite simply because you can only get these mats from salvaging armor and no matter where you are, the drop level of armor corresponds roughly to your character level. So if all your characters are level 80, then what? I can’t get low level armor except for grinding low level dungeons for tokens? I have to delete a character and level a new one up? Why on earth should level 78 armor drop for me from a Tamini in Gendarra Fields in the first place? The way I look at it, if I want high level drops I can take my level 80 toon to a high level area. I would think it would make more sense for the drop level of items would correspond with the area level.
