I got a Master Writ (excellent idea, btw...nice to be able to put crafting skills to use), and the writ I got was for the following:
Epic Quality, Prosperous Trait, Morkuldin Set, Skinchanger Style
Although I cannot craft Morkuldin set as yet, I don't have any issue with the first three requirements. However, the Skinchanger style requires a material that is effectively Unobtainium at this point (Wolfsbane Extract). I realize that I could buy a Crown Mimic Stone or get gouged at a guild shop for it, but I am wondering if having writs that require outdated styles is intentional or an oversight. If the latter, hopefully that will be fixed. Thanks.
