"Last but not least, we have decided to permanently turn off double experience and double skill gain after this preview phase is over. Vibrant communities with all the complexity, components and challenges like regular game worlds have evolved on Aurera and Aurora by now so we do not consider this initial experience and skill gain boost necessary anymore.
You can still benefit from these effects while the preview is active, though."

Guys, Aurora and Aurera will be no different from Danubia and Danera. It will become a 1x experience server like any other. People will quit and move to other worlds. New players on Aurora and Aurera will suffer greatly from the abuses of players who have taken advantage of double experience/skill for 2 years. People are already rooking themselves, people are already doing free tosses giving away millions.
If you have a character on Aurora and Aurera, SELL NOW before their values are greatly diminished.
