Server Three Guild War: Last Night, we tried turning over a city to another guild (Thunder). I assigned everyone to one city to face a different guild, with no one in the one we wanted to turn over. The result? One or two players arrived in the "empty" city and successfully defended. Annoying, but understandable.

Server Forty-Five Guild War: An ongoing issue. Players assigned to one city end up in another city. This really messes with plans and organization. Much more than annoying.
