That's the thing - basic wouldn't cut it. We are talking about a bunch of people who get kidnapped by a cult to become their "true souls". Who would you like on your side - a city guard or a badass barbarian straight from the Blood War? A grave robber or a vampire spawn? A random librarian or a former Chosen of Mystra?
Well, a city guard can turn out to be a badass in disguise... and the game is not all about combat, right? Cunning can do as much as brute force in a lot of situations. So can knowledge! I would not personally delete the librarian from the equation...
