I just really hope this Harbinger event thing works.
It's not that I don't care about it, but I'm so aware of why things of this basic type don't work well on me...
Super sandbox games require all your care to be about other players, but if you make it about combat/winning combat, then MMORPGs aren't really the best option...
So I think devs have to assume that they have to design it to have some storyline behind it even if maybe only half of their audience cares about any of it. Maybe a recognizable NPC or NPC group. Something you have to care about.
My example for this is that Throne and Liberty has recently started 'event-testing' their equivalent of FF11
Besieged and despite being mechanically on-point (I had the fortune of going to one with only like 30 players instead of 250), it lacks the gravitas, because there's minimal chance of losing (even with only 30-50 player defenders) and no NPC Generals or similar to worry about or protect.
This is a general 'shortfall' of that game at the moment, not quite enough 'time spent seeing how some character you have some connection to, is existing or relaxing in the same space as you'. They're working on it, but Ashes doesn't even really have that option right now.
It could just be that the intended audience isn't the type who is expected to care about characters like that, it's just a slightly weird (to me) approach to an MMORPG with this much Lore.
Without that, this event sounds like it will be almost entirely about players 'calculating what gives them the most gain personally' and then the masses who just follow whatever they're told, doing that, after all that would be the correct/reasonable response. If you only care about your guild/what your guild leaders say, and your Guild Leaders care about Dire Materials and Corrupted Drops more than 'stopping the incursion' or whatever, it might fall flat for 'my' demographic, unless it's genuinely a challenge and maybe even then.
TL isn't hitting the mark because it's not quite 'challenging' either, but like I said, it's more of an event-testing thing (they literally didn't even explain it, it's just 'hey here's a cool thing with some solo-player-ish rewards, jump in or don't) whereas Harbingers are a whole 'big update' for Intrepid.
