none of this post is correct whatsoever, it's actually impressive in a debased sort of way

This is 5th edition degeneracy. NWN is 3rd edition rules, in which case weapon finesse is working as intended, and correctly.

Weapon Finesse [General]
Prerequisite: Proficient with weapon, base attack bonus +1 or higher. Choose one light weapon. Alternatively, the character can choose a rapier, provided the character can use it in one hand, or a spiked chain, provided the character is at least Medium-size.

Benefit: With the selected weapon, the character may use a Dexterity modifier instead of a Strength modifier on attack rolls. Since the character needs the second hand for balance, apply the armor check penalty of any shield worn to attack rolls.

Special: The character can gain this feat multiple times. Each time the character takes the feat, it applies to a new weapon.

If Weapon Finesse worked as intended, it would be a straight downgrade from what it is: it would only work for a single chosen weapon type, any shield used would apply its armor check penalty to your attack rolls, and you still wouldn't get dex to damage.
