You keep introducing new Grind for only long term rewards... I can’t tell you how many new posts I’ve seen complaining about hours spent grinding with 0 rewards. I’ve said it again and again, the long term grind can get better but it is there — nightfall loot, exotic catalysts, raids. What’s almost completely missing is the progression based rewards that make the grind fun... the only thing that fits this is the exotic quests in warmind... that’s it... we need way more mid-level rewards and progression based rewards to make the grind enjoyable, while we keep aiming for that long term goal... otherwise it’s an “all or nothing” system, which frustrates even more time intensive players.
I think some of the issue with the grind we have not, along with the all or nothing as you so aptly put it, is the fact that everything is rng grind. There is very few persuits, maybe none in recent content that gives you a direct path, ie. clear x number of things and obtain y. Everything is a chance and we don't know the basis of that chance either.
