Perhaps. But, that’s probably a side effect.
The intent behind delves has always been to force players to fight rooms at their limits of capability, with extending that limit only possible through significant investment in hoards. However, crafty players were able to push far beyond what is supposed to be possible at this point in the delves’ lifecycle, as the likely intention was for them not to be cleared at anywhere near max level for a very long time. Yet, here we are. Darn those meddling players.
I still believe that in the long run, there’s going to be something that requires perfect 2500s in a faction that is significant. That’s going to require a level 500 clear with a faction team. And even then, that’s asking for Mission Impossible, because running a faction team in a delve against some of these rooms is equivalent to taking a full bounty team into Battle 20. You’re just asking to lose. I wouldn’t be surprised if a level 500 delve requires a level 500 hoard to even have a remote chance to clear with a faction team by design.
End game… back when 4.0 came out with the Underworld, I reached multiple conclusions about where I thought the game was heading very long-term (I think those were in one of my long rants on the 4.0 beta thread, can’t remember at 2 AM). Very much tinfoil hat territory, as there was no remote information to even qualify my theories. As of the 4.1 release, those are still in tinfoil hat territory, but none of them have been disproven as of yet and will survive until at least another quarterly patch.
That said, I do now have a tentative date in mind of when the other shoe will drop on delves, and that is late April - early May 2019, with the release of Spring quarterly patch. Why then? Because outside of an unlikely additional Overworld kingdom addition, the final Overworld kingdom without a base Mythic will receive theirs on May 3, 2019. (which will it be: Adana, Karakoth, or Sin of Maraj?) At that point, the Overworld will be complete, as I don’t believe that second mythics will be added to Overworld kingdoms (they are heading to Factions next). There will be still be weekly troops for events released, but for all practical purposes, the Overworld can pretty much run on autopilot at that point.
That frees up game progression to focus purely on the Underworld, which has been said by Sirrian to be the primary focus of the game for at least the next year (likely 3 years at one faction per month, barring some type of radical change). What form that takes… no one knows outside of the devs at this point.
But, my central premise that over time, in terms of end-game meta, that most Krystaran-based game modes and rewards which have not been monetized in some way will become increasingly obsolete, if not already there, to push players into the new mode equivalents [ex: donating to treasure hoards replaces donating for LTs for more relevant rewards; see recent threads about the “worthlessness” of LT rewards at end-game] still holds for now.
And now, it’s time for some sleep and a fresh roll of aluminum foil.
