I've said it time and again, but this is all a product of a fundamental difference of opinion on what Larian thinks "role playing" means.
They think it means they make a story, you pick one of their characters, and you play out their interactive novel and do the combat. This is the core of their games, their "origin" characters, etc.
Most of us more traditional role players think role playing means we define a character and plot a path through a more generally plotted world, with flexibility in how we act, who else is or isn't in the story with us, etc.
Resign yourself to the fact this is just how it is, because it's a Larian game.
