I only see US servers in servers list. I assume it's because of the fact that I use US account. So, to play on EU servers I will have to create EU account and download EU client?
Short answer: Yes. Long answer: I thought it was going to go open once the Beta ended, but I guess not then. The EU servers are Ceres and ... Lithcorp? If you don't see them on the list and can't expand the list to see them, I suppose a new account is needed.
