to place you retainer all you gotta do is go to the counter at the enterance to these smaller areas and click a place retainer. You pick a floor on the list, you get teleported to said floor and just ring the bell and place your retainer stall. each room floor can say fit 800 or more retainers. which can't be randomly places but places similar to how you placed mog house furnishings.

I hope this will make the areas neater less conjusted and easier to use. if not faster.
The auction how will be similar to ffxi but with a twist. Make it like a mog house where you enter your own personal zone where u can tallk to a broker who conects with the Auction house. (to limit that lag from ppl conjesting infront of the AH) (just a thought)
