Is there a deep metaphysical reason to this or is it simply the case of the Runes treating the Winds stuck in the Enchantment as their personal "All you can eat" buffet?
Enchantments and runes both change the rules of reality, but in different directions. Trying to have them coexist in one item is like trying to put an oven in your freezer so you can cook your food without having to defrost it.
