The Quanzhen Sect is undergoing changes, and the other Daoist sects aren't idling either, but the transformation of Quanzhen is somewhat radical, shocking to say the least.
To put it nicely, it's keen progress; to speak bluntly, it's reckless folly, a young man's fanciful leap that disregards the natural rules of cultivation; time will tell all, and everyone is watching as a troublesome Demon Sect collapses, which benefits all.
Compared to the changes in the Quanzhen Sect, the other Daoist sects first face the problem of harmoniously coexisting with the envoys from the Upper Realm, followed quickly by the problem of distinguishing between true and false envoys, and finally the challenge of making clear choices.
For example, what to do if two or more fake envoys come knocking? What if a real one and a fake one are in a fierce dispute? What if the fake is even more powerful than the real?
