I'd love to be able to explore Saint Mocianne's Arboretum.... That place looks like it would be really cool to explore. The first time I did it I was thinking how cool if dungeons weren't just one straight path and were more like the open world dungeons in FFXI.

Maybe in the future they can turn dungeons into something more closer related to how Diadem is in terms of how things spawn and respawn with multiple parties in one dungeon at a time, just bigger dungeons and random objectives to complete with different bosses to kill as objectives as well and bosses giving the tomestone reward.
