I feel like you guys talking about BA seem to forget one thing : Where it's placed in the story. By the time you can enter BA, your relics are considered finished (the game write that your weapon is complete before that step), and the story has an ending. BA is more like an epilogue, or the true end unlockable when you did some bonus content of the game. Everyone that missed FTB will feel they missed one chapter when entering OC part 2. That was not true with BA. The whole thing was more like a dessert you might not have finished, while FTB feels like we got robbed of one part of the main dish.
