When improving your weapons and then enchanting them, are you also taking potions and elixirs for both enchanting and smithing? It packs and even more powerful punch, along with perks in the enchanting tree, if you want the damage or armor rating even higher. I see your point of being able to do more damage than possibly intended, but remember leveling up these types of skills also levels your character, which is a good thing. You can level up all the way to 100 smithing just by making leather bracers and iron daggers. You can then also enchant those items with basic petty soul gems to increase your enchanting, and therefor character level, rather quickly. Enchant a bow with the soul trap enchantment, carry plenty of petty soul gems with you and kill mudcrabs and wolves until you're full. Then, enchant those daggers and sell for around 600 gold each to a vendor

Levels up skills, your character and also adds a good amount of gold too. Not sure if this entire post is completely relevant to your original post, but hope it helps some.
