I am hoping we get answers on why this data loss happened, and how Blizzard will address it.
Unlike the loss of the guild bank, there are many ways Blizzard can cross-examine old honor levels if this is in fact a full data wipe they cannot retrieve like the gbank loss.
One thread received a Blue response saying support cannot do anything about this. We need whichever people can fix it, to see these posts and reinstate the honor levels lost.
