a POP NM system like ZNM would be great. Lots of opportunity for this that could stimulate the crafting and gathering economy while providing an opportunity to revisit old content, underused zones and pull in more group activity outside of raiding.

Items can be dropped from certain fates and crafted with quested items. This pop item would summon a low level monster which would give you a seal upon defeted. That seal is used for the next objective to obtain a higher tier of pop NMs to chose from - or another "path"

Imagine if a requirement to pop an NM required a quest seal, a fate drop, a gathered item, and a crafter to meld the item together. This gives purpose to all disciples in the game and wouldn't break the economy or create hostile competition.

That titanic sawfish would make great bait for some high-level fight, and the HQ might improve your drop rate
