I think the change came with Shadowbringers, as that expansion seemed to be the plan change not Endwalker, assuming the goal to be entering the ruins and Emet's recreation of Amaurot. I think if Shadowbringers didn't happen, we'd still have Emet as the villain of 5.0 but we'd explore Thav and Garlemald and maybe Corvos and Werlyt, only to end up in the last zone which would have been very similar to The Tempest. 6.0 would have been a harder pivot to a bigger Sharlayan, with Elpis, Thule, and the moon relatively the same.
To gain Anima, would have required the sacrifice of Titania or Innocence. On the other hand, I think those that hated the way Elidibus was handled would have gone along with it better if he did his drama over fallen Garlemald.
But to further my real point here, the current iteration of Shadowbringers and Endwalker are reactions to the complaints about Stormblood and the success of Shadowbringers. We saw many people complain they didn't want huge zones like Ala Mhigo if they wouldn't be fleshed out well, so Shadowbringers gives us a lot of different zones that were very much different than every other zone and they adapted the story to this change. They then saw the success of this decision in Shadowbringers only to hear the community claim they wanted more Garlemald and more Elpis in Endwalker and didn't think the story adjustment to having very strong different zones adjusted to the story went well enough.
To give a smaller example is Viera. They added the race because of overwhelming player request but Hrothgar as well because that was their original plan. Giving us the situation where we had female Viera and male Hrothgar. And although they have listened to give us the gender swap for these races, the community hurt the lore and plans of the Bozja storyline because we didn't have a female Hrothgar to take on the role of the queen of Bozja.
We should be very careful about what we ask for. They do listen to us, but we should be very specific about what we want to see and not want to see. We should also not get caught up in meaningless arguments here either, as we are just hurting the direction of the game because we are letting unchecked feelings guide the direction of the game instead of well thought out criticism and suggestion.
