I get you now .. you wish we could craft it from the raw materials so it would fully be 'our' creation. I totally agree because it would just feel more awesome to know that we made the armor from animal furs and leathers, then upgraded it. I would be more attached to my armor that way too.
i use to craft fur armors before the patch, i think the patch removed the creation of fur armor by the player (let me add this up on the top post).
I was wondering that also. Fur should be down there with hide armor, completely craftable and all that. Maybe it's because there are four different varients of fur armor and they didn't want people wondering why the other armors didn't have any different versions.
one way to help for us not to get confused is to renaming it. but why do that? when you can see it visually.
