I think Larian just leaves our own background up for ourselves to decide. The only thing set in stone is that we are baldurians. Which gives the players the freedom to make up their own backstory.

Gotta say I think its a weird thing to complain about but maybe giving us more options to set our background in stone could be helpfull. In pnp dnd your background also gives you some features that you can use. If you are a local hero people know you, if you are a sailor you can get easy acces aboard sailing ships etc. Something like that could help.
