Also there is a important condition about how this game will go on: "Playable for everyone"
Yes, one thing that Larian wants (every SH wants beacause it's important to survive in actual videogames market), is to make Baldur's Gate 3 and D&D mechanics in general just more appeal and ideal also for Newbie-Friendly. USe a 20 years-old mechanic with late '90 videogame mechanics is not so newbie-friendly for today standards.
