I just realized that it is in fact WE who are being farmed, lmao. The whole design concept of zero end-game, plus seasonal, resetting content with a resetting battle-pass is a means to endlessly monetize the consumer base.
From a narrow field of view there is no incentive for them to actually add end-game with which players could run all the way into eternal realm with a complete gameplay loop.
For this reason I do not believe a proper end-game loop is ever coming.
I mean there is more of an endgame compaired to D3 and its under a year old 
Definitely more than D2 as well, but that’s not hard to do considering D2 had no endgame.
@Galactic of course they want to make money, they have multiple expansions planned for the game, those aren’t just going to make themselves for free. Although objectively speaking, knowing the history of the development of the game, current issues, lack of content, lack of QoL, etc. it’s a bit of a stretch to assume this is all one big corporate plot to get players to pay more and more and keep the content gated.
Now the more likely reason is the game was released too early, and they’re trying to play catchup. It takes several years, of actually working on the game mind you, to make something worth playing. I have no doubt upper management wanted the game released as soon as possible considering how long it took to develop, even if the developers didn’t want to release it just yet. But no employee is going to come out and ridicule the very company they’re working for to the public. They’d quit first, then get interviewed by the Washington Post.
The only thing I will say is D2 felt like more because there were items to chase if you were not a credit card warrior of playing trade sim but you are correct. D2 was just farming bosses although some items were rare. D4 no longer has rare items because they went from lottery items to uncommon but there is more content.
