1st off, In the interest of crafting or smithing itd be nice to have a higher level cap and naturally more armor and weapons.
As well it would be nice if we could craft arrows in the future, bound bow aside theyre a real pain to keep looting from the dead or paying for and could make more use out of a lumberyard.
Following with the ideas of crafting your own equipment and such the idea of being able to run your own shop that you can stock with said equipment, as well hire some friends to work. Gaining customers through social interaction advertising using speechcraft to determine the success rate.
And of course perhaps some more spells. They are quite neat.
