That's Future Rogue's future though, going by how much of a shell she was of her former self I think Future Lucy's future was different.

Its probably not even a full 1% in her future going by her and Future Levy looking as if all their courage and hope is gone. (A trait that doesn't fit those in Fairy Tail, that really shows how bad things became)

And due to the conditions for each of their futures being present (Since the gate was opened and then closed), its likely that now we have a 3rd future that the story is heading towards. So its likely that the knowledge from either of those future doesn't work now.

It feels like we need to see what happened to Acnologia during the Dragon Civil War to truly understand what's going on.
