I dont want to use the frase "dumbed down", I will just say that enchanting has too many restrictions, compared to the previous TES games. I cant enchant gloves and boots with any fortify magick school, or with magicka regeneration? Whats up with that? Now my mage run around with plain boots and gloves, because of the limited enchanting system in this game.
Bethesda, what wre you thinking? It worked fine in Oblivion and Morrowind. Why would you try to fix something thats not broken?
Enchanting is powerful as is. Some say it's OP. You want to make it more powerful? If they allowed enchanting everything on everything, you will probably make a different post about how OP and broken it is and how it was so much better on Oblivion and Morrowind. To me, not having played Oblivion, restricting enchanting for certain items makes some sort of intuitive sense. What is one part of the body that is least used for casting magic? I would say feet.
But you are right about the fact that there is little that directly benefit a pure mage on feet and hands. I'm playing a pure mage who does not do enchanting, and the best thing he found to wear on feet are a pair of boots enchanted with shock resistance found at Archmage's quarters. Since, I'm a Nord, if I could enchant shoes myself, I would enchant it with Fire and Shock resistance. I don't have anything on my hands at the moment, but if I could, I would enchant it with Fortify Magicka and Fortify Sneak.
