They mean does the game world react to what subclass you are within the story and dialogue. It was a response to my post where I made the assumption that it will not. It is indeed an assumption, but I personally think the game will just react to your class and not your subclass. I could very well be wrong.
Ah, thank you for clearing out my misunderstanding.
Considering that NPC reactions are all voice acted and the huge number of story permutations, reacting to all subclasses (at least 3+ per class) would be way too much. Some subclasses, though, are "special" like which god a character worships or which pact a Warlock has. It is already quite huge.
