They can tweak values like NM spawn rates, exp per mob, and reduce/remove the exp penalty, but they can't "fix" Pagos at this point. The whole of Eureka up to now is fundamentally flawed. It's nothing more than a zone to grind mobs in so you can level up to have higher raw stats to grind higher level mobs so you can level up more. That's it. You don't get magicite to enhance your character in a meaningful or interesting way; you just get a defense of attack boost if you rock-paper-scissors the elements right. Eureka, much like Diadem, is creatively bankrupt. Unless they can develop content that is more meaningful and creative than "grind mobs to level up to grind mobs" as a end-game max level activity, then there's no way they can actually fix it for any reasonable person.
