As it stands right now, quest rewards are far too weak when compared to gear crafted with 100 Smithing and enchanted with 100 Enchanting (so without abusing the Alchemy vs Enchanting loophole).
i stopped reading there. you have no clue what you are talking about thats for sure. otherwise you would not call this thing a LOOPHOLE because a merely 3-7% stronger entchants are not really a loophole a loophole is something that can be repeated endlessly. (whats really a loophole is the thing with restoration potions THATS a loophole because you can repeat it endlessly)
the problem is that failthesda forget to assign some items (like the artifacts and the nightingale blade for example) to a fitting smithing perk. that is a oversight. they did it with some items (priest masks work with STEEL perk) and forgot it on others. thats called a BUG.
there is a mod already out there that fixes this problem tough.
the ebony blade for example has either THREE bugs at once OR which is way way more likely and makes more sense when you look at its stats has only ONE bug and thats that it is actually supposed to be a ONE HANDER. the later is much much more likely considering how easy it was to assign a weapon to a weapon type back in morrowind and oblivion. a simple MISSCLICK by some dev could have done this which is more likely than all the other THREE things at once on the same item.
what kind of damage do you guys who flame the crafting part actually think would be OK or BALANCED ? let me tell you this : the game is already pisseasy with a weapon who deals above 200 damage. and guess what`? you can get a weapon that has this damage by only using the fortify weapon % entchant on it. no alchemy/smithing/entchanting perks needed for it actually. all you need to do is this BUY some things of a few vendors at all.
and that is all that is needed to reach this high numbers already.
failthesda will never REMOVE any of these effects entirely the only thing they could do if they actually THINK about it is making it so that these entchant effects no longer STACK that would slove the zero manacasting aswell. but that is the ONLY way to balance this thing.
and i really really doubt that bethesda will see this option so they will leave it as it is. and there a more important things around than these imo. (endless oghma use for example)
