I don't disagree in premise, but...

Eureka and Bozja have some of the strongest longevity of any piece of content released in this game, period.

It's not as popular as it was on launch, but that is hardly a surprise, really. Any piece of content is going to wain over time, but both Eureka and Bozja have stood that test and have enough players and popularity to actually be a good experience.
