I confess I actually chuckled at the underlined bit.
There's way over a 100 million people playing mmo's.
However, as a solution to more content? stop subbing - unless you have something to do, but I personally refuse to pay US$180 for a game per year that I even purchased the expansion / paid development for. Content has been very scarce and lack luster in my opinion. I just feed my nostalgia every two years for a month or two whenever the specials on expansions come out.
To each their own, however.
