Guys, I'm sorry you feel that way and I used to as well, but after spending a lot of time playing the game and also reading a lot in r/dndnext over the last couple of years I've realised that D&D has a lot of imperfections. There's no point slavishly recreating it RAW. Even the developers have regrets and are doing surveys to see what people would like changed in 5.5E – which at this rate will come out just after BG3. So even if BG3 was a perfect adaptation, it would only be rules-accurate for a year at most. WotC is even deprecating short rests, based on the most recent books where all the racial short rest recharge features have been changed or removed.
