I am surprised that the LoL event did not start at rollover! Would have been the standard rythm, starting with warrior LoL and concurrently to the sac event. Maybe it is just postponed for a day or so, as we have this cosmic lol dungeon? I always like the overlap between LoL grinding and sacrifice.
If this is not the case, we might indeed have one week of relaxing "LotB holiday" so to speak until the next event
