I was involved in some areas of the beta, and I can agree with those who say that WoW is still a classic MMO addiction, but that it seems that I can come back to it as I want to and not feel like I have to grind it out all the time.
It's much more geared towards casual gaming than other MMOs, with various ways to make the grind pass easily, and different hooks into making soloing easier, whil still providing raid and party content for those who wish to dump a lot of time into it.
It's more down to an issue of whether or not you think you're going to play it enough to make it worth $15 a month in extra funds. If you're going to, then you don't have to worry about anything. The fun and the community will take care of everything.
