I feel like the AQs drying up after the archon releases outside of like 1 interlude, maybe a second archon SQ and a Dainsleif quest really contributed to the issues that resulted in our Nod-Krai pitstop.
Doing nothing with the main plot for half a year after like 3-4 months is rather silly. You could've replaced the multitude of festivals with some more Dain quests or AQs/SQs that tackled the underlying celestia/khaerni'ah reveals alongside the World Quests and lore books.
