I think it would be pretty cool if you were able to have some kind of Mount crafting. What I mean by this is not to actually make a horse but maybe have some kind of horse breeding or be able to customize your mount like being able to create the Saddle, Horseshoe's, Change the horse colour, maybe even put an enchant on it to make his eye's glow red and look more evil or something? And also be able to sell the mounts that you create. I don't know maybe it's a little to much but I think that would really set this game apart from other's (not saying it isn't already) but I don't think something like this has been done before.

Anyway those are my thought's on Mount Crafting please feel free to add some comment's or even add to this idea, Cheer's!
