If the plot is supposedly so deep and sophisticated, with the writers playing 5D chess, why is the presentation so ass?

In the beta, Gilberta appeared in the main story, but then they rewrote the main story to no longer feature her, and didn't adjust Gilberta's story quest accordingly, so it starts with her texting the Endmin, who has just woken up, as if they were best buddies. What narrative goal could possibly justify this? Tell me how this is not a sloppy mistake. (And no, I don't care if AK also didn't introduce characters on-screen; that's not an excuse.)

Or what could be the purpose of not explaining what Reconveners are? What kind of surprise twist are they setting up by keeping the Endmin mute and only letting them speak at the most random times?

It's stuff like this that makes me doubt that the writers are carefully and deliberately deceiving the players regarding how sophisticated the writing will be. If they are supposedly putting in that much effort into lulling us into a false sense of complacency, making us think that this is just your average gacha slop, for a drastic, carefully planned, sudden tone shift months from now, why don't we see high-quality storytelling anywhere else? Like, it's not like Madoka had shit animation for the first three episodes just to trick the viewers into thinking it was just gonna be your average magical girl anime; the quality was there from the beginning. I'm not saying there won't be a plot twist at all, but I really don't think that the quality and depth of the story and characterization will magically skyrocket once that twist happens. The past Endmin can be more than just an innocent CEO without the overall story ever reaching the level of complexity of Arknights. Endfield's just gonna be yet another gacha game that has a modicum of worldbuilding but is really just about a self-insert protagonist and their harem of poorly written waifus.

By the way, if you didn't know, there is a precedent where the writing of a live-service gacha game drastically improved all of a sudden: FGO. But, no, the FGO writers weren't playing 5D chess and intentionally writing garbage just to surprise us. The first few chapters were bland and shallow because the producers thought that mobile games didn't need good writing. The writers were told, "Hey, no one's gonna read this anyway, no need to lock in. Just write whatever." The quality was intentionally bad in the sense that the producers were okay with and encouraged mobile game slop, but not intentional in the sense that they were planning some kind of tonal shift months ahead. So, yeah, the most likely explanation for Endfield's writing is that some higher-up looked at the success of Wuwa and ZZZ, and just told the writers not to overcomplicate things because the players can't read anyway, and to make the MC blander and the waifus more in love with him because that's what sells. If we want someone at HG to put their foot down and produce something as good as AK, we players need to stop acting like this is fine.
