Anyone get the feeling "duty support" will be "for quest only?"

[Omedon]

So I bit the bullet and made an alt purely for experiencing a game that does some form of trust-level AI dungeoning from level 15 on, because trusts were literally a key reason I abandoned WoW for FFXIV. As someone who started MMORPGs with EverQuest, therefore having a first impression of dungeons as being "for connected players only" (which I was not always), and then experiencing various communities who took automatic group assembly and thus their fellow players for granted, the novelty of being able to run dungeons at will on my own is euphoria. But that's not what this thread is about.

From what it looks like, "duty support" is just "scenario mode" (which became an immediate unlock per dungeon completion as of Endwalker) renamed. As an immediate unlock, and as we all know and appreciate now for the level 87 dungeon in particular, that makes it an infinitely repeatable and enjoyable leveling path for job after job for the levels where that dungeon is the most relevant. As someone who literally levels every job with some form of trusts as of level 71 right now, reveling in this status quo starting at level 15 is worth making another alt for...

...*IF* duty support is infinitely repeatable.

I rolled an alt under this assumption, but did anyone perhaps pick up anything between screenshots and interview/liveletter minutia that might suggest anything to the contrary? I didn't look as close as some of you might, but before I go all in taking this new alt's entire class spectrum to level 15, I figured I'd ask if there was a detail I missed. I don't *think* duty support will only be active when one has a quest, particularly now that scenario mode gets unlocked on dungeon completion, but... did I miss something? Or can I likely safely assume it's infinitely repeatable?

Thanks in advance for any and all helpful replies!
