While Executive Producer Lance Stites took time to address some of the most prominent issues raised in the Aion community last week, we want to specifically address another issue that is a top priority for the team here at NCsoft: in-game real money trading (RMT) advertisement, sometimes referred to as “gold spamming.” These activities are something we’re actively combating right now. They are also something you can help us with, and something that we are committed to addressing continually in the future. 

Today we will be adding two additional servers.  We will be adding a new French server named Arbolu and a new English server named Kalil.  As we continue to grow and add more servers we realize that switching from a queued server isn’t an easy decision.  In order to incentivize play on these 2 servers, as well as the recently opened German server Lephar, we will be offering 10 consumable experience potions that boost your experience by 20% for one hour.  These will be available through the survey system to one character per account on these servers and only for this weekend!
