Since you can change jobs on the fly, having a place to go to change jobs isn't as important. Storage is another issue, however. You can store items on your retainer and you can call your retainer to you in all of the cities UNLESS you are using your retainer to bazaar. If you have set your retainer to bazaar in a market ward (the only place you can leave them out), you will have to go to them to get your stuff. Not very convenient right now.
There are some changes coming that will make this arrangement more feasible. We should soon be getting the ability to have more than one retainer. (I don't think I saw it with the November update list, so it will probably be in December.) Also, the announced anima reduction for teleporting will make it easier to visit your retainer wherever they are.
I, also, liked decorating my mog house in Windy, so I hope they will be adding that as a feature. It will give the woodworkers something to do with all that lumber and planks.
