This game has always had a lonely feel at these large places since I started playing. When I played WoW I used to love walking into Orgrimmar. You could feel the atmosphere somehow. With the auction house crowded with people to everyone standing by the mailbox. It just seemed alive.
The should have less instances for ESD, DS9, K7, Starbase39, memory alpha, and where ever else to get more poeple on the same map. Yeah the lag sucked when walking into Orgrimmar before they got a handle on it.... but it felt alive.
