The issue with short-term content

[BabyYoda]

Eureka and Bozja are far from dead. Both are actual pieces of evergreen content that people still run groups for today.

There's a say in the Eureka community: "Eureka never dies".

And that's still holding true. There are still daily runs of Baldesion Arsenal and Delubrum Reginae Savage and activity in both sets of overworlds. So, I would cross those off your list. One of the few reasons I'm holding out for something in DT is that there is a new Field Operation in the pipeline.

It is a community effort to not kill old content but there is no systematic approach to it.. it is like ok we know SE consider this mood as dead but we want to give it another life.

Which is great but it is a community effort no developer effort
