I think the problem is that the story of Baldur's Gate 3 isn't Tav's story. In most crpgs with a blank slate protagonists the protagonist is the main character. BG3 isn't about Tav, it's about whichever character the player happens to be controlling. That's why the Dark Urge isn't a solution for most people (combined with the visceral violence which certainly kept me away). People say that Tav needed their own unique backstory stuff because otherwise they just have nothing that makes them special. In every other crpg, the main character has their own unique story; it's called the main plot. The story isn't actually built around Tav, so Tav feels lacking. It goes back to my first point, that Tav isn't meant to be a character you roleplay as or get invested in. They're just the tool you use to decide what content you want to see.
