Now I really hope that Larian will focus on creating world that feels alive / "real" for their next games (unexpected encounters, day and night cycle, map design, less gamey fast travel system, coherence between the different layers). IMO that would lead their next games to "best rpg of all time".
This is the missing ingredient from a perfect RPG.
Larian's RPG's biggest flaw is that it constantly reminds you that it's (just) a video game. The goal should be to make the player forget and just get immersed. E.g. theme park maps are very convenient, but they break the 4th wall when the game is so aware of the players convenience that it has illogical distances.
