We have the world bosses which spawn at somewhat random times. What about expanding this to other kinds of dynamic events? A Troll assault on Isolated Sentry Post outside Calpheon: Players have to defend the node from a horde of Trolls. An assault of Candidums and Black Rusts on Lema Island: Players have to defend the island from sea monsters. An emergency timber shortage in Trent: Players have to collect and deliver timber for an NPC in Trent. A Shai going on a rampage in Velia: This would be automatic lose. There's no winning against the Shai. Worker strike at Ancient Stone Chamber: Players have to collect and deliver beer to workers so they'll stop their strike. Basically, dynamic events which start at any point (like the world bosses) which involve a variety of mechanics. And of course, there would be some kind of reward attached to any of these events if the task is completed and you participated.
