I think one of the things that need to be said is that Larian wants this game to also be accessible to people that have never played Dungeons and Dragons table top (which is why they may be using a lot of DOS mechanics). If you bombard a new player with rules and rules and more rules, you can wind up alienating them by making them feel like this is more for hardcore DnD 5e players. We all know that every company always wants new customers as many as possible. Which is why they will make changes in order to attract new customers/players even if the ones that have been there from the beginning may not like it. They should understand that in order for a product to remain popular the company needs to attract new people. In regards to wanting Baldur's Gate 3 to be RAW DnD game, you risk limiting access to players that have not played a DnD game but may be interested in this world setting. In order to draw someone into something, you have to gradually introduce them you don't want to bombard them.
