Whatever the Prophecies manuscripts may be, I think we can agree on that the Forgotten really do seem to serve the Gods, rather than Glint. One of the interviews with the devs seem to basically expliitly mention that.
Quests in the Domain of Anguish, post-Nightfall, shows that things are going in a less-than-optimal setting. I should probably go back on the Wiki and finish up some of the missing dialogue. At least two separate quests have last-stand-esque styled missions, and one of the in-quest dialogue even have the guy you're supposed to escort state that they're the last of their race. One of the other quest-giving NPCs state that the Margonites overwhelmed them and pushed them back there to one of the outposts (same guy who gave you a list of the demons they fought - I just can't remember his name off the top of my head), etc. In sum, they need the PC's help because Mallyx is absolutely wrecking things.
A lot of really depends on interpretation, and I think it fuels discussion. My interpretation of the Forgotten (again, just an interpretation) is based on some in-game circumstantial statement saying that people all over Tyria tried to come to ascend, only having failed to do so. Their motivation for helping you, the PC, seems to stem from the observation that you are part of the Flameseeker prophecies rather than out of any desire to "help" you achieve their goal. In that sense, they were more closely aligned with Glint, who also have her own agenda. Between that, and interactions with the Margonites (who can't possibly be positive. If anything, the Margonites ascended too, and we know that the Margonites were also in the Crystal Desert even after their banishment since they built those structures), my interpretation is that the Forgotten can't be terribly warm to humanity after all of it.
