FFXIV's RAM issue: Solved next expansion?

[Skivvy]

I ran a simulation in my head about how this would look & feel if we spent 30seconds or about a Minute running across water to a giant castle which design is fully rendered in the game in a seamless transition....
Conclusion--- it might be cool....the first 2 or 3 times. Otherwise, id feel like its dead air and wasted time from playing the game and Id end up bored and do something else while I wait for the dungeon to continue. After that first 2 or 3 times of AMAZING IMMERSION, id ask why did they do this instead of either pulling the castle closer so we are wasting less time here, or why cant we just teleport to a new zone?
Basically...the Praetorium.

As I see it (and I COULD BE SO WRONG), they can make these grand backdrops because they know they'll just have you zone into the castle, so no biggie!. If they were to opt for seamless dungeons, there's no reason why they'd have to keep this as a huge, empty waterway that you simply run across.
