I don't think that's fair. Drew is a mature enough author to know that when you set up a cliffhanger, like the end of Reclamation, readers expect it to pay off. Kahina and Hassan went out looking for the Rift at the end of Reclamation. Maybe THEY have already found it and we're just playing catch-up. I think Drew is clever enough to find a satisfying way for us, the players, to unravel the mystery without ruining an important plot point for his upcoming novel. Besides, Kahina is far too imperfect to ever be mistaken as a Mary Sue.
I think there are two problems that the Rift mystery has, from the point of view of both author/developers and the players, that are an obstacle to solving it pre-2.2 (who knows what clues we'll get in that...).
.
The first problem is that it has been possible to find since launch so, theoretically, it could be solved by anyone at any time (Drew has said something before about being hopeful that a lone wolf pilot just figures it out, or words to that effect as I understand it). That means any plot points the author/developers decide to plan out could all get thrown aside in a single forum post with supporting screenshots/video. As players, it would be bad if it were like the recent Hunt and that was it, all over and done with. This is why Drew has said it's not a POI - it won't be over and done with if
it is found: it will be more like finding the first step. An analogy might be not so much trying to find our way out of a maze but to find the entrance to one from outside. There will be more to the mystery for us to investigate (even if we have to wait for the next update).
.
The second problem is that the mystery is so obscure it is going to waste a lot of players' time investigating it, when we have no idea what we're really looking for, or where (to any significant degree of accuracy). There are a lot of really smart people here and in the Canonn but it's not like someone who reads Reclamation immediately knows to go check out systems x,y,z and post screenshots of whatever it is that's meant to be special there. This is a game design problem more than a storytelling problem: as I understand it we are being warned that another civilisation, advanced enough to be a significant threat, is operating in the vaguely-defined region of space known as the Formidine Rift. The game does not provide much for us to discover that would reveal the presence of such a race, without POIs like space stations and alien ships in supercruise, which, as described above, are not what we are looking for, at least not directly, for now. Therefore, we have to depend upon the 'right person' just noticing that something is odd when passing through the right area, be that an unusual concentration of Earth-like/Ammonia Worlds or systems with depleted resources or something else. It is quite possible that, even then, they might just dismiss the discovery as an oddity and move on: even someone who had read Reclamation might not realise it was what Kahina et al. were looking for.
.
The end result of the two problems is likely to be that the story moves on without us finding the solution. (Sorry for the pessimism - I just think the odds are stacked against us solving it, as 2 years of searching has found nothing). That does not mean that we need more clues, it just means that the story takes a different branch. Another analogy (from what I've read about another video game story Drew's involved in; I've not played the game itself, though) is like the Lords of Midnight game: you have a realm facing invasion and limited sight over your nation's land, so you have to search out the location and strength of the invading forces; fail to find them and the entire army can suddenly show up on your doorstep and trash your kingdom; find them in time and you have a chance to stop them, or weaken them enough to defeat them later. If we fail to solve this first stage of the Rift mystery then events might move on and we will have other things to look for. If there is another civilisation out there that has designs on our territory, they might be building up their supply lines and as they gradually close in on us we might find these 'signs' in places closer to home than the Rift.

From the perspective of 2.2 arriving, I think the locations of the Sirius probes in the EAFOTS region and in between EAFOTS and the bubble are going to be noteworthy. Perhaps they may find something before we do...
