I think it would be nice if weapon damage increases from smithing could scale in proportion to the weapon's base damage, or at least have different damage boosts for the different weapon types, such as swords, waraxes, maces, warhammers, battleaxes, and 2 handed swords.
As it stands right now a fully smithed sword deals more dps than a fully smithed 2 handed sword, and given the drawbacks of 2 handed weapons this just svcks.
