Not everyone plays DnD you know, and learning ruleset just to play a single game seems bit much to expect from people.
In all my life I never played a crpg where I didn't have to learn rules, and I don't want to. If Larian wants to make a game where you don't have to learn any rules, that's their prerogative, but it's not what I wanted when I paid 60€ for a game called Baldur's Gate.
