Did you remove the enchantment before you sold the sword back, if you didn't already have the formula? You may not want to use it now, but if you have the formula you at least have the option of doing so later.
Even in the original release of D2:ED many people thought intelligence based warriors were better due to the availability of balanced and magic weapons and a better stat bonus to damage (that's part of the reason I went with a strength based warrior). In DKS the damage bonus from intelligence was made equal to strength and dexterity, but the other changes make magic damage and enchantments much more effective for warriors and mages (the best bows do mostly conventional damage so rangers are best served with a high dexterity, though the magic damage enchantment was always my second choice if a bow had more than one slot).
