Ever since Bungie did Marty dirty and "allegedly" mistreated Joe Staten, they have not been the same.
I can only say allegedly mistreated Joe because it is former Bungie employee hearsay and not legally verified information. But still, after hearing that Jason Jones Frankenstein'd the Destiny that Joe wrote with his friend's fantasy project (I think it was called Minotaur), and basically took all the credit for Joes work, yeah I have been soured on Bungie.
The Dreadnaught on Saturn, from the Taken King expansion? That was originally planned content for the end game area of the initial release. Bungie really did cut up Destiny and sell it back later as DLC.
Not to mention vaulting the entire campaign (and DLCs) that D2 originally launched with. So if you bought the game on launch, you don't even have access to the content you paid for.
That explains why everything after taken king felt like garbage, they didn’t have their creative to steal from anymore and ran out of his ideas. Destiny 2 from the start was a terrible game and it only got worse over time. Then they stole the entire game people originally paid for and gave them nothing in return and I never played it again.
