Here’s a holiday I really like! On your first time through, most of the achievements are fine. Nothing really requires grinding, and the only annoying achievement is School of Hard Knocks, requiring you to PVP with your orphan. It’s hard to PVP during Children’s Week because a lot of people are there only for the achievement.
On a character that already has all the achievements, the holiday is simply three quest lines. Do I need to do them? Not really. I got some Magical Pet Biscuits, but I wasn’t even expecting them. I did the quests because I enjoy seeing these moments. I especially look forward to the Bronze drakonids attempting to attack Salandria. Best of all, the quests can all be completed in less than an hour.
