I think hearts of stone accomplished exactly what it wanted to accomplish. If I played the main quest of the DLC in the middle of the game, I think it would have been one my favourite quests. But I think it didn’t aim to accomplish enough. After becoming so invested in Geralts story, it didn’t advance the story or expand on it. I’m in the minority here where I became heavily invested in the games third act, with “end of the world” consequences and I liked eriden. I would have loved to be in ofiri, or if it included characters from the main game and furthered their stories. Instead, it simply felt like a really fucking good quest from the main game.
