Gating interesting content behind artificial side leveling

[BillyKaplan]

In this very interview he says the public dungeon is not "casual" content, and casual players should avoid it.

There's casual in the sense of what content they run (not savage and extreme) and there's casual in the sense of how much time they have to invest in the game. It sounds like the content is not for casual difficulty-wise, but is gated behind content that is not for casual time-wise. So the two axes are not really related, and this is yet another way for them to force people into Eureka, because the one bit of content that's worth doing out of this mess is at the very end of a long haul that people otherwise wouldn't be touching with a stick.
This really isn't comparable to "clear Savage before running Ultimate" because if you're not the crowd that runs Savage, you have no business in Ultimate in the first place. This isn't the case and Yoshi himself set Eureka and the dungeon apart in that last quote Nora brought

You could use your logic for the other side as well. If you're not the crowd that runs Eureka, then you have no business doing the Dungeon that is tied to it in the first place.
