Same here, during the story we dont spent so many times with the characters we love so why dont give us the chance to spent our time in post main-story with them.
I'm agree with you and many others here, we dont care so much about the world to change just want them back with some interactions (hunting (Ciri), romance,qwent etc.) JUST FOR NOW so we can all return to the game and play it.
Then maybe in a future is CD Projekt RED want to do something more complete they could add new quests like Ciri's training or someting else like more dialogs and so on. BUT for now just put them on without changing the world.
On twitter, Marcin Momot and CD Projekt don't answer when I talk about Ciri, Yen, Triss come back
Why they don't answer ??
