ANet wants people to clear out their inventories to promote trade, rather than keeping 'cool' items to themselves.
Instead of seeing it as a cheap way to exploit their existing customers for yet more cash, they are merely trying to improve the game! Unless of course you pay them, then they don't give a damn what you do with your items.
With the planned release schedule for the expansions (at full game prices), the lack of a monthly fee is not even a valid argument anymore.
How long until we pay for patches?
