Bummed because you never found that Orc female, or one of the other rare races?
You can actually still complete that achievement, so long as you have the item that puts bunny ears on them.
Confirmed from the Customer Service Forum today. Even if the holiday is over on your server, you can still finish that achievement (for now).
I guess I should let the angry people over at WoWinsider know… or, it can just be our little secret.
I managed to complete the Noble Garden meta achievement a couple days before it ended. So, I don’t have anything else to worry about… except that pesky PvP achievement for Children’s week. I might just never finish all these things…
