Seriously... some of us don't like to "play the market wards" when we log on.
I want to be able to run up to a market or auction or buy/sell/trade or shop or whatever you want to call it counter and buy what I need, get it on the spot, and go do my thing without playing "check all the star retainers~" and "oops! you're in the wrong ward" or my favorite "lawlz look how cute this gear is on my retainer for 9999999999gil '-'r like for surrrrre~"
