I didn't have a problem finding a plot...but I also knew the spot I was looking for. I got on friday night. went all the way to the vale of shadow entrance. plots around there were open till the end of the test. Housing in the finished game will be much different since you can build anywhere in freezones- what are also full loot. or get lucky and get a claim area. what has it's own upkeep cost. Most people will live in towns for NPC guards/ item protection or claim plots for the same reason.
