Have you considered that I don't want to play someone else's story? That I don't want to play Larians vision of the Hero's Journey but my version of the hero's journey? What reason would there be for this option to not be available to me if not the main focus of the game? If I make a custom character I am making that character to go on an adventure and it's my adventure. I want to be the hero. I don't think that is an unreasonable or big ask especially because it IS early access and now is the time where they can change it without having to retcon later.
I mean, they DO offer that. That is what the custom character is. They aren't going to remove the origin characters' stories just because you want to play El Generico and not have anyone interesting in the part. If they had a pre-prologue before the mind flayer abduction where you were made to fight some giant rats in the inn's cellar or however El Generico got his/her/their start, would that be better?
