Since the timing is good for suggestions on this topic, here’s one concept to kill two birds with one stone:
Turn the disastrous market wards into player housing.
Let players buy their own domain in one of the (renamed) wards. Retainers would “live” in the player’s house, and would still hold their stuff. The bazaars and item search feature could be kept, but improved (i.e. directly port the potential buyer into your house hall from the search menu, and fix the multiple little annoying things). Linkshells could also buy their own complete wards level, and control who's in it.
And while we’re there, add the option to buy farms at the remote Quest Hubs where players could hire another retainer who’d grow things and raise animals. Players would also have to gear and rank up their retainers to defend their farm from beastmen. These farms would also have stables where players would put their own chocobo. Chocobos would have bags, and could be called out in the fields to carry stuff back and forth between the player, farm and house.
And while we’re still there, add moogles that could be called up to carry gear sets. Moogles could be linked to the future job system, being the Grand Companies helpers from the past eras.
And, finally, make Kazakhstan a peaceful country.
