Patch 4.0.1 Leather Worker ChangesPatch 4.0.1 brought about many changes. With the removal of the specializations, leather workers are now free to learn the recipes that were currently only available to your specialization choice. There are no more tribal, elemental, or dragonscale leatherworking specialties. Leather workers should stop by their trainers and pick up the 4 new recipes.
Careful Crafting These
I was an elemental leather worker, so I was able to grab 2 tribal and 2 dragonscale patterns. They require either 260 or 330 skill to be learned from the trainer. All 6 of the old specialization crafted items appear to be bugged. The crafted items are still showing the specialization requirement and thus are unwearable by any characters since no leather workers have a specialization anymore. These patterns may end up being removed completely. Weaponsmiths suffered that fate on all of their patterns that used to require the weaponsmith specializations. Wouldn't suprise me to see these 6 leatherworking patterns disappear in an upcoming fix.
The following recipes have been removed from the game since ammo is no longer required.
The only ammo pouch to stay in the game is for Quiver of a Thousand Feathers, although it only requires 99 feathers to craft. The quiver is now a 20 slot BoE bag, which puts it in competition with Frostweave Bags. Looking at the materials required, don't waste your time crafting the quivers. They have much higher material costs.
