this is irrelevant to xtrade, the dev put that tax for in game economy reasons, you guys thinking it's to somehow discourage xtrade are barking at the wrong tree.
2nd point, the buyer pays the tax when xtrading, just like it is on IQRPG. (IQ even has a higher tax at 5%).
this is the info I was seeking, I never traded in IQ and just wanted to see some community feedback here on how we should roll from now on, so thx for that!
and yeah, the last swarm produced lots of gold and there are probably more reasons why this should be good for the in-game economy
