The final achievement I completed was already a four for one deal, since completing the continent completed the fires of the world, which completed the Fire Festival, which completed the holiday meta. I decided to throw in one more achievement for good measure.
|What a long strange ding it has been|
Overall, the holiday achievement grind was nowhere near as bad as it was back in 2009, when it pretty much literally drove me out of Azeroth to pick up EQ2 (which I suppose has worked out well enough). I'm still not convinced that limited time holiday events are a good place to put a grind, but at least the current system is something that you can do without going too far out of your way. Other than the torch thing that I had to cheat with an add-on, and the hunt for a female dwarf for the creepy Easter achievement, there wasn't anything this time around that was actively non-fun to complete. If you're looking for the occasional change of pace from the daily (quest/dungeon) grind, I suppose there are worse ways to go.
