I don't think people should get so worked up by large cuts... I recently looked into the development history of Baldur's Gate 2, and guess what? same story, huge cuts of tons of content. in a large scale game such as this it is to be expected. for now, I think the focus should be only on making what is in the game working perfectly. If something was cut, it is probably for a good reason. and it might be used in the future if enough work was put into it already. even if Larian themselves won't do it, we might see something akin to KOTOR2 cut content mod.
but then again, I'm not sure things are this bad in this case, as far as I see, it's merely a matter of buggy flags. although I do wish some early choices would have more impact.
