Nah. No thanks. There are already 3 "Battlecraft Ward". If one is full, just put it in a different ward or in another city. That's whay the game gives you a big warning that you will be closing stands and yadda yadda if you remove your retainer from there when you try calling it somewhere else.

And if you just feel like having it sold in a full ward due the taxes, i'll tell you a secret (more like a bug than a secret lol)...while your character is there your baazar is affected by MW rules too. Just put what you want to sell there at your character's baazar and leave him there when you go AFK.
