Dungeons are becoming style over substance.

[Absurdity]

I have always felt that the major reason of dungeon simplification is that they cannot be bothered to do proper coding for the Trusts. More complicated mechanics will just be more complicated for the Trusts.

While I believe that it was certainly part of the reason that ShB dungeons are all just the same dungeon with a different coat of paint, the same can't be said for Stormblood dungeons.
