The Global Trade HQ is one of the worst trade systems in any game platform I have ever seen. PLEASE, change it to a ASK/BID system where you can request to buy specific items at a set price as well as post specific items for a set price. Remove limitations on cost, or at least expand them greatly. It will not punish new players - it will actually help them as expansion and storage items will be more valuable. With this game, many, many, many gaming hours are spent refreshing the Global Trade HQ searching for specific items. This one change would greatly reduce frustration and greatly improve game play satisfaction.
