I use to have weapons that strong, but they kill in 1-2 hits and it's really boring and nooby. So I nerfed myself and my sword is at 155 with enchantments.
My main Character uses an Ebony War Axe which only does something like... 56 Damage.
I've only upgraded it to 'Superior' as my Smithing is pretty low, and that's the best I can improve my weapons to. My enchanting is really low too, but I don't really use much enchanted gear, apart from my Vampire Boots, which have a Fire Resistance Enchantment of about 26%, and Vampire Gloves, which have a Magicka boost of like 20 odd points.
I play on master difficulty too. Although, I have now replaced my One Handed Skill (
as I maxed it) with Destruction and Conjuration. I'm basically playing a Mage now instead of a uhh... Healing Warrior? I only used Light Armour, One Handed and Restoration. Now, I use Destruction, Restoration, Conuration, and Light Armour.
But, anyways, I do agree that when you Improve your gear to to idiotic amounts of damage, the game gets a bit boring.
Fair enough to those that enjoy playing like that, as some do, but it's not for me.
