What is the rationale for being so adamant about not overhauling the Global Trade. What is the fear?
You still have yet to address the biggest issue of all: I am offered something that I cannot buy. I have spent the last 2 days trying to by 1 expansion part. Just 1. Probably 3 hours total of playing. Can't buy 1 lousy expansion part. I get to see it in the GTHQ once in a while, but those llamas always have an accounting error.
If you are going to offer me something to buy, at least make sure I have 5 seconds to buy it. There is nothing more frustrating than your own architecture/framework that prevents an integral part of the game from working. I would gladly have only 4 random choices to choose from - if I knew I could actually buy the item.
There is even a splash page that says use the Global Trade HQ to buy and sell the things you need. You should remove that page since it is a blatant lie. You cannot buy what you need. It is a farce.
