I think it isn’t lazy. It’s focus: the mission hints at the characters’ past but doesn’t unfold that information completely because it’s not particularly relevant to the mission. It’s a nod to their backstory together.
What is a problem is that in that mission I never found out what the Algorithm was supposed to be until like the tenth run-through, when one of the characters (I think Phoebe?) triggered a conversation with ISIC where he explains it.
Otherwise…well, all of the missions are self-contained stories within a background (the Varelsi invasion thing and Rendain’s deal with them). It’s less of a campaign and more of a compilation of unconnected missions.
I think the major problem is that the Heliophage comes out of nowhere if you haven’t read the first comic. And even THEN it feels like they all go:
“Well, that’s enough unrelated missions while we waited for the Heliophage to be done. Oh, did I mention the Heliophage is a thing? It’s a thing. And we have been waiting for it to be completed. For…some reason.”
It feels like they wanted to retroactively explain why all the other missions happened and the reason is ‘waiting’ for a thing none of the players knew was a thing they were waiting on. It was never foreshadowed, never mentioned before, there’s no build up, and it comes out of nowhere. The campaign could probably use like four more missions to build that one confrontation up. The unconnected ones are fine, mind, and have their own place (their place being the same of any episode in any TV series; there’s no arch for them, they are just there for the fun of it), but the final battle is lost in the noise.
