I think comparing one MMO to another is stupid. Of course a lot of them share the same types of content, they're in the same genre! That's like saying Team Fortress 2 is a Call of Duty clone because they both force you into one of two teams and let you shoot people on the other team, or Jak and Daxter is a Banjo Kazooie Clone because, in both, you have to beat up enemies and collect items hidden all around one large area before you can proceed to the next large area.

I mean, doesn't it sound more than a little stupid? Or am I just taking crazy pills?
