I like the idea of creating trade hubs in addition to the existing portal hub. I am wondering if it is possible to keep the Imperial consigners in the locations they are now, but make them non-global, and then in the hubs make them global and website searchable.
The reason I would like to see the consigners remain in non-hubs is simply for the sake of immersion. Tazoon is supposed to be the biggest, most bustling city, yet it is essentially abandoned. Don't start putting other racial capitals into the same situation.
