Keeping humor out of the main narrative is something i strongly disagree with.
This is a larian game, humor is part of what they do.

Humor does enhance a narrative.
For me personally, most recent games that tried to go super serious actually had me care less about the story.

Id actually like to give a very *odd* example of Humor in a main storyline since its from an MMO.
Anyone here played the Orsinium DLC for ESO?

One of the main Characters of that DLC, King Kurog has this extreme juxtapose between humor and seriousness. On one hand, he kills people on the drop of a hat, on the other hand you can see him eating half a roast pig because he can, sitting in his own cornerclub because hes a king and he can do what he wants.

Its a character that, surprsingly for an MMO and for a TES game, actually works realy well.

Trying to be super serious rids you of opportunities and makes you look like a try hard.
