This is the real reason why we have so little and buggy content. Save for not having enough time which was true. But the reason for not having enough time was because they rebooted midway in its development. Anyway, that's the link to the post that I read the shed some light on the issues.

D2 was postpone by over a year.. They most certainly had the time to make sure these changes were in game from day one.. These are add-ons they gathered from our complains because the game is dieing within its first month.. Otherwise wed probably never have seen these changes

That’s due to Bungie’s inexplicable need to restart projects in the middle of development. Happened with Halo 1 & 2. Happened with D1. And it happened here. If anything was a hinderance towards Destiny as a franchise, it’s the upper brass and them, I’m banking on as to now, still having no earthly clue knowing what Destiny really is.

Bungie has 3 years since destiny one dropped of course activison pulled their leg but keep in mind 3 years is well enough time to you know make hard mode raid weapons

The live team is only minor stuff.. Like events or adding ornaments.. Anything else is done by the Devs.. Basically what Bungie is saying is that they're done with D2 except for mini events form this point on.. DLCs made.. Weapons and armor is made.. Exotics all done..
