FFXIV's RAM issue: Solved next expansion?

[Absurdity]

I mean, I'm not willing to sacrifice dungeon complexity just to avoid a loading screen or two, if it came down to the choice.

I certainly would agree...if we actually had any dungeon complexity instead of pretty window dressing on a long corridor.

Castrum Meridianum have some of the "amazing sprint" you are searching for, but it seems it wasn't exactly what everyone wants. Maybe a few, but not everyone. Maybe it is ok have a loading screen in this case.

I'd argue people have more of an issue with the annoying, sometimes completely pointless, cutscenes interrupting gameplay than the size of that dungeon.
