That's... exactly what I was trying to say. If you have to rely on older content to keep your player that have done the old content occupied, there is a problem with the new content. I didn't mean there was litterally nothing to do (I don't think I said that anyway), but that compared to the ShB patch, content EW patch kinda feel empty.
Since it's 2.0, they always gave us a lot of storylines during the patches, giving us several thing to expect in new patches. Now we have less of them, despite most of the content is still there. By making all the trials part of the msq, we lost the trials storylines. By Frankenstein'ing the relics weapon to the already existing Hildibrand storyline, we lost the relic storyline.
HW patches had 6 storylines : MSQ, Raids Alliance, Raids, Trial story, Relics and Hildibrand (I don't know how the Ydillshire reconstruction worked, so I didn't count it).
SB patches had 7 storylines : MSQ, Raids Alliance, Raids, Trial story, Relics, Hildibrand and Doman reconstruction.
ShB patches had 6 storylines : MSQ, Raids Alliance, Raids, Trial story, Relics and Ishgardian restoration/diadem.
EnWalker has 4 : MSQ, Raids Alliances, Raids and Hildibrand. You could add the Tataru quests (probably should add the shcolasticates quest in HW or post roles-quests in ShB then).
Content is still mostly there, yet with each patch it feels more empty. When you look at the the storylines we have no equivalent or replacement for, a lot of them are long running content (Relics - Or at least Eureka/Bozja, people ran that even when not doing the relics -, Doman reconstruction or Ishgardian restoration). Add to that that the new content we got did not have big longevity. Island Sanctuary ended being a management minigame that takes you 10 min a day at best after a few weeks, Deep dungeons is a reskin of older deep dungeons that were never really popular (Sky pillar can be a pain to get into) and Variant dungeon was nice, but you can easily complete it in a week if you take your time. I think that's part of the reason the reception of EW patches is lukewarm at best. There is not much to expect and to be excited about for 6.4 and 6.5.
We have a mmo based on story telling that "cut" long running content and the number of storylines it gives us. I hope it's because the ressources are allowed to redisign of old dungeon to make the msq doable in solo, the graphic update and the 7.0. If that's the case and it's one time thing, I'm fine with it. But if it's a new philosophy that will continue with 7.X patches, I think it might be a problem. Afterall, this IS a MMORPG and having long running content is part of the experience. It's not about getting Eureka/Bozja like content to do, but having something to return to on the long term.
