Should Moogle Treasure Trove be Permanent?

[Atelier-Bagur]

The treasure trove is permanent tho, it is called grind cause you can get everything from there through the normal way. If you are too lazy for that or you don't have time to grind old tribes etc. then well wait for the next treasure trove event otherwise go and work for your stuff like the rest of us did.

Doesnt necessarily have to be old stuff, there can be new rewards
