What steps could the devs take to better the Open World in XIV?

[Iscah]

Of course, given how weaksauce overworld mobs are in this game, they might as well all be passive...

It feels a bit like the main thing aggressive mobs achieve is constantly interrupting the zone BGM with the battle theme. :/

They act as gates to higher-level areas in ARR where it's physically possible to walk into the Lv50 area at Lv1, but the expansions are a lot more restricted by the story already.

Also, "highly dangerous" B-rank elite marks are left being the sole non-aggressive creatures in the entire zone.
