Clearly they aren't interested in that, these are brought up every time the game slows down or a new expansion comes out, and they're ignoring it.
So unless they're planning an expansion level update as a season, I doubt they'll be recovering lost ground any time soon, if ever.
Some of the QoL changes are definitely needed that we've seen, but I mean....those should've been added at any point over the past decade, even just the prime engram focusing and making them unlimited rather than weekly. There were so many low points where adding that in would've revitalized people's interest but it's gone on for so long most don't care anymore. Or at least *I* don't.
Don't forget, they wouldn't want to [i]overdeliver[/i]
Unfortunately they are quite slow to react, but we have seen Bungie respond to player feedback fairly often over the past year so anything is possible.
It often feels like they aren't listening but most likely there are people still passionate about the game and are being held back, much like the overdelivery mentioned.
Still strange to me that such methods are considered promotable but you may be right that the upper management is truly too far gone at this point.
