So Blizzard seems interested in maintaining the peace between the faction for now. Which is ok, sure why not. But Blizzard can easily have their cake and eat it to by allowing us free access to the timeline where the faction didnt stop.
It would be the perfect excuse to see the two faction due it out story wise/for adding new battlegrounds while not affecting the peace between the factions. From what little we did see of this timeline it could probably tell some pretty interesting stories.
