They won't because of their concept of origin characters.
Origin characters HAVE to have the same story as custom characters.... But they can also have side story.
That's Impossible with custom except if they create many specific quest related to a class/race/pre-defined background. That would mean create something like 5 to 10 "origin stories" only for custom character, which is impossible.
They bring this absolutely bad concept from DoS into BG and just because of it... Custom characters still won't have any specific background or story.
This concept is absolutely evil as soon as you're talking about custom character and it will always be.
Yeah, im not a fan of Origin, I never will be because of various reasons, but I don't even mean having Origin stories like Dragon Age Origins, I know that'a fantasy because that is a tall order. But literally ANYTHING would be better. A single story, like they were doing SOMETHING there, or atleast some mandatory NPC you come across that asks you about your life and you can tell them what you were doing before this like they do in Pillars 1, because that is better then nothing imo.
