Suggestion: Level 50 treasure maps with portal dungeons

Not sure what the general forum consensus is on this, but I'd like to see level 50 treasure dungeons at some point. The rewards could be commensurate to the earlier portion of the game to keep radical things from happening economically but, this gives newer players a chance to get involved in a fun activity with the rest of their FC's and may give a new kind of life to zones that may appear dead or unused to new players and give them a goal to work towards they can see early on.

Gil rewards dont need to be outrageous but little deco items for an apartment may be nice. Thanks for your time.
