I’m not sure if this has been suggested, but the Trading Post has become a dumping ground for all sorts of items. Thousands of items selling for below vendor prices. Obviously posted by people not paying attention, or just leftovers from launch. Either way, my thought is to put a time limit on each listing as other MMO’s do. Perhaps a 3 or 5 day limit and then the item is returned to the person that posted it if it hasn’t sold.
I think that will get the economy back on an even keel rather than allow folks to absolutely flood the TP with useless items by the hundreds. I’ve seen stacks of thousands of low level armor and weapons. Please clear this stuff out to keep the market moving!
