If I use a mod to tweak difficulty, it's usually to change a bullshit challenge to a reasonable challenge. There's so much BS in games that make it harder, but in a dumbass way. Like, you do hardly any damage but the boss can one-shot you. So I would mod it where now you aren't one-shotting the boss, but you're also not using a super soaker against a demigod. That's not a fun challenge, that's just lazy game design. Literal brute force over making the NPC behavior more clever and complex.
