Why do you care so much? There are people who are really enjoying the server the way it is.
You can always go play at Siel if you want a more active server.
Plus, the server is not even two weeks old, you expect a server to be full from one day to the next?
Let's be aware that those of us who play Aion do it mostly for the love of the game, we are veteran players and many are already advanced in Siel, so they don't see a reason to start over again in a new server.
