Hi people, and hi staff team! Before i ask my question i will explain my motivation.. This is not news, that xrevolutonx94 was moved to red server because he "donated alot" . I do believe he donate alot, but i don't feel this is fair to another players from yellow server, unless they also move to red in near future. We should have equal right to move from yellow to red? No? So here is my question: how much one person need to donate to this game, to be able to move to another server ?
