I don't understand why its so hard for Bungie to make content. I can't think of any other studio that is this incapable of creating new things for their already established world, tools and gameplay. Especially since its debatable if anything that was DLC for D1 was actually even made after D1 launched. (DLCs 1 and 2 were factually in game already, I gltiched to them pre-release, 3 and 4 could be seen in trailers and pre Vanilla release footage.. I say they only added the 'story' and spawned enemies)
And that's not even getting into the EDZ from D2 also being in pre D1 release footage and the assets in early D1 PVP maps.. And virtually no new enemies either!
Because Content isn't really the problem. The problem is the value cycle.
If I made a game where the goal was to earn money and I gave you 5 activities to chose from.
Play a mission - 10 minutes
Play a dungeon - 15 minutes
Play in the sandbox - 5 minutes
Play PvP - 10 minutes
And everyone of those activites gave you $100 in game bucks, what have I just done? I've made 75% of my game obsolete. This is going all the way back to the launch of Destiny 1. The loot cave was a product of the game starving the players of rewards. At no point in Destiny has the playerbase ever really felt like they were swimming in rewards (I take that back, year 3 iron banner where you were getting purples at the end of almost every game was great).
Bungie's philsophy seems to be keep everything out of the players reach, because the only reason they'll come back is because they're all completionists. I argued against this point back in they day, because players who want everything is not the right demographic to balance your entire system around.
I know Bungie has all these grand plans for everything over the course of this year, but something they could do now, as in a patch could be ready to go next week, would be to adjust loot values so that everything drops way more, and your rewards are based on time invested. The former should literally just be adjusting some variables, the later might take more than a week depending on how their system works.
