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.
This is where I think Bungie have a real problem to deal with.
I feel the complete opposite of you and I don't know what the middle ground looks like.
As someone who does not care about the light level grind - there are more than enough rewards pouring out of everything I do. Public events, adventures, PvP, Strikes - you name it, it's raining glimmer, loot and experience.
The problem is, none of it matters or feels unique. I have nearly every exotic and legendary item and they're all the same. And more importantly, the things that are good - Mida, Nameless Midnight, Better Devil etc. Are also so easy to get that they don't feel special.
The only stuff that is somewhat interesting/scarce - are cosmetic and usually tucked behind Eververse. Again, pretty meaningless.
I want to have to earn the best guns. Make them tough to get and even tougher to upgrade. Give me some ownership of my guns too. You want an ornament - go and kill 500 people in Crucible with it. Want to upgrade reload - run 10 strikes using it.
Having everything behind RNG is boring and it has only become worse in D2.
