If Virtue is any example, the new server code isn't ready for prime time. Talos didn't seem as crowded as you would see during a rikti invasion, but the lag was worse than I've ever experienced. Several minute delay to try to get on a train to switch zones, then another several minute delay when you switch zones before you can actually move. A minute or two to activate a power. Major rubberbanding while trying to move around the zone. I don't know how many people were in the zone or the server, but it definitely wasn't playable.
