FFXIV dungeons are a little bit too linear?

[Morningstar1337]

As long as we got tomestones and the like, dungeons will never get any more complicated than what we have now since people will revolt if something takes too long to complete.

And if Tomestones cease to be, people will claim that the game will be "harder" because they now have to deal with RNG to get their gear for the raid, Morton's Fork...

Of course I would like to see some 8-Man dungeons below Raid level like say an 8 Man version of the 24 man Raids, something that can't be added to a roulette and could provide a midcore craving a well as an opportunity to make non-linear dungeons (but a little more linear than Diadem). They would even make actual HM versions of the dungeons that need 8 people and rename the existing HM dungeons as "<dungeon name> (Phase II)" or something to that effect
