Like alot of players, the "good Stuff" you'll more than likely find in Player character's Bazaars than in the market wards. (at least i seem to) SE need to realize and stop adding resources to the wards, no one like's them.
IMHO~ the wards should have been made like an Online Shopping website, your retainer should be the window to the AH, store info on what you most look for on the AH and bring up your most common searches, ie food, crafting materials weapons, while also allowing you to browse the whole AH for other stuff.
Then the original factor - bazaaring stuff! you place them with your retainer who puts them on this AH database which sells them.
You also still store items in your retainer like you would your moogle in FFXI,
I'm sure this would drag people to the market wards in their droves and actually like it. The wards in turn could just be a personal preference then of which one to choose, sorta elieviating the lag on 1 specific ward, allowing for example 300 people to store their ward before it closes. and no one else can gain acsess to that ward. (3 pages of wards think its 5 wards per page, so 5x3 = 15 x300 = 4500, thats more than enough space for a server full on wards)
You'd have what they tried to offer witht he original retainer system but more User friendly
FFXI : Ryobi & Ryder Asura
FFXIV : Bracken Wood Gridania-Balmung
