I would love it if you could skin animals/creatures and use those skins and things to craft armour, cloaks/clothing out of. Actually have the things you can craft LOOK different depending on the type of animal it is and certain unique ones for rare animals. Like having wolves and then having a rare big white wolf you find and making a pure white cloak from it's skin and having the head rest over the top of yours like a cap, that'd be cool.
this was in bloodmoon in morrowind.
you got normal bear and wolf pets to craft into armor, and special snow wolf/snow bear armor to make into special armors.
you also could mine ice armor.
in tribunal, you could craft ebony, glass, and adamantium armors by mining the raw materials.
i would be happy without skinning if we can use the pelts/creature specific drops to take to a crafter for armor.
