Balmung may have the least number of characters created, but im confident its still the busiest server. It spent most of the last 2 years being unavailable due to congestion or locked as an over-populated world. As a result, the RMT bots and spammers who got banned were actually removed from that server rather then just making new toons over and over like they did(and still do) on most of the other servers.

Meanwhile, at this point houses are reaching their minimum valuations. Still over one hundred available on my server, including one or two mediums(goblet) last i checked. Successful patch on the housing front, but clearly not perfect.
