Larian never promised to implement gameplay ideas of random people from the forum and they should never do that. They wanted feedback, which helps them know what features people like and what dislike but Larian will be working according to their own vision, not a vision of some angry forum poster. Obviously some feedback on feedback would have been great but I understand why they want to keep silence. People just get angry if they are bluntly told that their ideas are horrible and won't be implemented.
