I think this game is perfect in almost every way except one.the game has so many items that it is hard to know the approximate value of everything. I think this game needs a market demand based trading system. Have some central outpost made just for trading items. It could be in a place like the temple of balthazar where no mater what game you have you could still get to it.
At this place you could load your items that you are looking to sell. the key is that when you put your item for sale you would get a market price guide of what the item has been selling for. if the item has been selling for alot then the price you see raises. and vice versa if the price in the market has been falling. You could leave this item in this special storage untill it sells.
on the other hand if you are lookin to buy an item you would see the same price the seller sees. From here you could set a max price you are willing to pay. You would upload your money into the exchange untill your item you are seeking becomes available.
The price would flucate by the supply and demand of items. If there is a large supply and little demand then the market price would fall and vice versa if the price would rise.
I think this would solve alot of issues. It would get rid of most of those annoying selling post and it would help playersof all levels buy and sell items.
Let me know what you guys think

Leave GW1 like it is, if you don't like the current system of trading go play another game or wait for GW2....
