You do realise that content 'missing' is because those development resources are poured elsewhere. Firmament and Ocean Fishing are prime examples. Those aren't just pulled out of a tinfoil hat and magically produced. This argument just comes down to preference largely (Oh well I like Deep Dungeon, but I don't like Bozja, or vice versa), and if they were to continue release the content just because "was there last expansion" - Then that's just a recipe for stagnation. If they released another Deep Dungeon and it failed to innovate on previous iterations beyond renaming pomanders, or adding in new magicite then it would just be for the sake of routine. - It's like, do you feel they're just pulling Island Sanctuary out of a hat? No that's just content being introduced at the expense to content elsewhere in the game. I feel like if they just released another deep dungeon just cuz, or kept to the same routine of dungeons and didn't introduce the large scale delubrum raid with savage difficulty, nor the 2 other raids we got alongside of it then this argument would very quickly turn the table of going from:
Well they're cutting content > Well it's the same old expansion and no innovation. This development team in the past has been criticised for their lack of risk factor, or for their stale routines, it is an argument that I agreed with, and to be frank they innovated content a little more with Shadowbringers.
I'm not going to blame that on anything, I'm just going to tell you to stop selecting content areas that have been cut whilst subsequently ignoring areas where content was added, or new. It's a disingenuous outlook to have, whilst removing many of the merits that came from it. I guarantee you if they just maintained their standard format/routine, then this thread would not be created by you. But in it's place a new thread would have been established criticising developers for their lack of innovation/risk. They took a massive risk by trading off content from previous expansions to develop relatively entirely new experiences, and something they can innovate on going forward, as they did learning from Eureka to produce Bozjan Southern Front / Zadnor. They've already openly admitted that not producing a Deep Dungeon didn't produce their expected outcome, and would you look at that, they're producing one for Endwalker.
