Its coming and it looks like all but four of the achievements are do-able. Sadly, we need all four of those for the Elder’s title. To get the 50 Coins of Ancestry, we need to do some of the Cataclysm Elders, which I have to get the flight-points for. Considering the holiday is over 2 weeks long, I’ll just get them as I go.
Also with 50 coins, we can purchase either a Festival Lantern or Lunar Lantern, so pushing for the 50 coins is definitely worth it imo. It does however mean you have to make a choice of either spending 50 coins for the pet, or 5 coins for the Pant Suit achievement. Hmmm.
