Recently from a well trusted person, information was leaked that we can customize are creations in various ways.
These ways include being able to add aesthetic effects as well as internal effects during weapon and Armour creation as well as with upgrading.
For example, i could have an iron dagger and add a wolf pelt handle, giving it that signature taste that everyone so dearly wants.
We don't know much information about it, but i have high hopes and can not wait to see what we can do.
Here is where i got my information, a very well trusted source.

Don't forget either.
Enchanters you may not be ruled out of aesthetics either.
In a interview about a month ago it was said that elemental effects, actually appeared aesthetically on weapons (Maybe even armor?).
This means if you enchant fire damage into a sword/arrows, you will see the weapon/arrows have fire dancing around them.
