I honestly dont know if it would get better or worse.
However...as to whether or not traders should pay pirates...
Guys, at least listen to the offer. The worst that happens is you RP, dont like the offer, and try to silently run away like you were planning to do from the beginning. Except, without the silent part.
Also, why is it that people seem less inclined to pay when you ask for less? When I used to ask for 2mil apiece, More than half of the traders I found would stop and RP, and mostly pay.
Now that I ask for only a few hundred thousand, or a few hundred units of cargo, most people wont say anything other than "screw you".
