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.
Funnily enough, Swen seems to be in complete agreement with you. Throw everything DnD that is not an immature fratboy fun out of the window, make DOS 3, slap a "DnD!!!!111" sticker on it, sell it to unsuspecting audience (preferably through Steam, as it has an almost non-existent refund policy) and count the money!
He has a good business head on his shoulders, that Swen, I give him that.
