I'd like to change the "last generation of this weapon" recipe requirement to "last generation or greater of this weapon". That way if you had a shocking edge (or any other recipe) that you already bound to yourself you can use it to make another shocking edge that isn't bound to you.

If you have a Faust but want an avenger you could use your Faust in place of a sealed sword in the avenger recipe.

Either that or allow me to downgrade my sword to whatever it was before I upgraded it.
