Fail.....you are failing answer me something will you? what use would someone that has all there needs already met and exceeded by there own production have with selling and buying stuff on the market?

To put it plainly little to none...besides ALL the GP only items if they was to be sold would cost alot to begin with there would be no getting around that really we would be talking about someone spending real money on imaginary money the exchange rate would be a matter of common sense about who that would favor.

Did you miss the fact that no one has even mentioned the idea of ship upgrade artifacts being trade able in fact they shouldn't be they would be way way to easy to abuse if you could some super high ranker "sells" them to a low rank buddy and all of a sudden we got 500 rank 40 people in Goliath class ships running around
