I would agree that MMOs in general are a time sink, but I am not sure I can absolutely equate that with a waste. There are some things I learned playing some MMOs including real microcosm of market psychology, interesting uses for linear regression and even some basic scripting. One of my best friends is effectively a result of a chance meet in an MMO. And that is before the argument that time enjoyed is hard(er) to label as a waste.
For the record, I agree with you in general, but I do not want to overgeneralize and add some nuance, because I do not want people to automatically say game time = useless. Tons of leisure activities do not yield immediate dividends ( reading books come to mind ), but are not without benefits.
Minor disclaimer: I am typing all this as an MMO recovering addict ( it got to the point where it was interfering with my work life ) so some take my opinion with a grain of salt.
