I feel like the main reason many people were disappointed is that we were hoping for a campaign that would be a continuation of the amazing story and characters from the base game. The DLC by itself was legitimately enjoyable and worth the price IMO, it's just that people were expecting a miniature Throne of Bhaal or something but got a (still fun and interesting) disconnected spinoff with clones instead. It's good, just very different from what people were hoping for/expecting.
I know this probably will never happen, but I and probably many others would absolutely love to see a true sequel game/expansion that follows the adventures of the Commander/companions after the battle with Areelu. I can understand that it might be rather difficult to account for all the various ending possibilities though. But honestly even just some expanded ending slides and maybe even a bit of extra companion dialogue in the base game would make me very happy.
It's unlikely we'll see a full sequel, as the story is logically over, plus, as you correctly noticed, story branching (and as a result, amount of work) grows exponentially, which leads to exponential amount of work.
A bit more content for mythics (especially late game mythics), expanded ending slides, more voiceover and dialogue etc. are a very possible thing for Enhanced edition though.
