I just had a great idea and wanted to share with the community, I wish you could create your own dragon priest helmet and armor. Both light and heavy, using, for instance, the dragon smithing perk. Think about it a custom dragon priest helmet made of dragon bone or scale with your own enchantments! It's genius!

The ability to rebuild already built parts of your house (I.E. Hearthfire dlc housing). Adding larger scale creature bosses like the Lore Giant Mudcrab (imagine one emerging from the ocean while traveling along the beach), notably dangerous and large sea creatures preventing you from turning your back while venturing to far out at sea! With the double enchantment perk I wish I could add a second enchantment to already enchanted items, for instance to the Volendrung 'hammer of might' or Morokei's dragon priest mask.

Well. For starters, welcome to the forum.

This is Elder Scrolls Online section, I assume you wanted to post it in the http://www.gamesas.com/forum/117-v-skyrim/. As for your suggestions, since Bethesda is done with Skyrim and won't add anything to the game, I guess they are interesting mod ideas (or food for thought in the http://www.gamesas.com/topic/1473826-official-beyond-skyrim-tes-vi-27/).

And yeah, I wish we could double enchant already enchanted items too... Not artifacts though, they aren't entirely under our control after all.
