Tbh...
I think having Forked Tower is fine.. Setting aside the fact that the developers seem to have an inability to reflect and act properly on their own mistakes.
But honestly... I think the issue is that they have pretty much diluted every other piece of side content, or neglected it outright, which does lead to a very... Empty experience overall. So what they've ultimately ended up doing is trying fairly hard to funnel players into content that they don't want to be doing. Like, a lot of people just don't realize how much of the games experience they have actually abandoned and diluted.
In many respects it's literally the same issue that Endwalker suffered with..., the only difference being they've shifted satisfaction from 1 side of the player base to the polar opposite... Which is really not good (Even setting aside my own personal interests), as even after 12 years they still don't really know who they are exactly designing the game for.
