New system to allow treasure chests to very rarely spawn in random locations

[Mizunoko]

I think it would be fun to implement something like this where very rarely a treasure chest could spawn in a random location somewhere in Eorzea and a lucky adventurer just happens upon it while doing other content and open it to maybe receive a nice rare item or something. Please do not confuse this with the hidden map/treasure hunting system which is specified to the party doing the maps. What i am talking about is open world and not instanced or anything like that. Kind of like a hunt monster where anyone can happen upon it and take it. The current treasure hunting system is fun and all but it has less of a sense of actual luck and rarity as all a person has to do is simply buy a map go to the location and dig it up. I think with a more rare chest spawning in random places would be fun because then people would actually have to look or be able to actually discover it like real treasure instead of being told where it is. I'm not good with words, however i do hope what i'm trying to get across as an idea made it to you. Thank you

Ahah I've thought about this since way back in the 1.0 days.
Exploring the sprawling overworld, I've always wanted to come across something rare and exciting like that. Instead it was level 99 efts that wanted to eat me.
