Yeah, no, sorry, as nice as a spin you can put on it, you won't be able to convince me of that. As someone who already beat the game, I don't think I should have to replay chapter 14 (or any other chapter) two! more times in order to see additional story content, specially when storytelling is the number one thing the game has been criticized for.
If story and storytelling were solid in the base game (like they were in most of the previous FF games), then sure, no problem with adding hard to find events.
But when the game's number one criticism has been it's lackluster story and storytelling, and if the developers are really interested in improving said aspect of the game, then scenes like these (as in, scenes with characters who were barely present in the game/suddenly disappeared from the plot/fans have been asking more content for) should NOT be this complicated to find.
