It makes me sad that there probably isn't even a point in sharing feedback like this anymore, since they have been so openly decisive about being done with the game.
I'm genuinely happy for game devs to have projects they're passionate about working on, but I think BG3 deserves more than being hurriedly and permanently pushed aside before it's reached it's potential in a truly satisfying way. I believe it's a disservice to an incredible game. It's disappointing that it won't be getting the same care that DOS2 was given after release. The way the main quest in particular in act 3 is structured leaves much to be desired. The potential is there but the act feels rushed and incomplete in many ways.
I wouldn't want the game to be worked on while the devs are burnt out from it, but the door should have been left open to improve upon it at another time. It doesn't need DLC but I believe the game itself still needs work and care. I had hoped BG3 would have a lasting legacy of care given to it's conclusion on par with The Witcher 3, but I don't see that happening now. Not when the devs are in their own words "elated" to put it behind them. It is a little heartbreaking to know that a game I've been deeply invested in for years is being tossed away with relish. And it does make it difficult for me to be excited about their future projects. If a game as beloved and successful as BG3 is being left behind in a less than satisfying state, I'm cautious about getting so invested again.
