Many users across most of the servers, both in the U.S. and E.U., are reporting long queues again. While the population always seems to uptick around this time of year, one has to raise an eyebrow at this happening a second time in as many months.
November was understandable. Wrath was a big deal. But after a week or so the queues died down. Is this just the second insurgent of Wrath's wrath?
One can surmise that a large number of people received Wrath as a Christmas gift. The assumption is probably correct. Another popular theory is that with all the vacation time on folk's plate right now, people are using it to log into the game and enjoy a bit of Northrend adventuring.
