While Aquapolis is great for farming gil, its best for capping lore due to how quick and easy it is. Everyone in the party can get 2 maps and you wont be done with all of them by the time you hit your weekly cap of lore.
Not to mention its great for materia and shards/crystals/clusters when you get treasure goblin or argus spawns.
If anyone were to farm them for gil it would be people who do not have a crafting class that pays for itself and otherwise have a harder time making money.
