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.
Meant that in context of not having respec needing to design character build before playing. With respec you can just play the game and fix build issues at any time.
