9. Turn based combat. There were quite many disputes about it on this forum. Let me say this, I can esily assume that BG3 will be at least 200+ hours of game time (completionist). Now imagine you need to spend 5 minutes or more for each encounter. Not for me and surely not for BG3 the continuator of previous installemnts that worked in real time. But if you really feel like you need to make TBC make it optional. I'm sure it is possible and not that hard. Why? Because someone managed to made mod for PK and if one person can do this, whole game studio can do it to.
Bingo.
We'll see if Larian was smart very soon.
