FFXIV dungeons are a little bit too linear?

Thing is if they just removed their "Invisible walls", despite how much SE loves them, dungeons (and the world) would become so much more open instantly. No resource cost there.

Until you figure in that it's highly unlikely that areas behind the invisible walls have been checked for collision & trap problems, out of bounds entrances, crash-causing texture errors, etc. I remember how long it took to debug simple Quake levels to ensure things like the above didn't creep in and that was far, far more simple a setup.
