we lose the ability to decide that we will sell to X for 40 gold, but to Y for 60 gold. Or that we will feed region X for 40 gold, but refuse to feed region Y even if it offers 60 gold.
You can do this--there are new restrictions on "sell only to your realm" or "sell only to your ally". and, of course, you can simply choose not to use sell orders at all, but instead utilize only buy orders.
