Personally think you missed a lot of fun additions to WoW but then again everyone is different, that's your choice. If you look at WoW it really did nothing majorly new that wasn't done before either, compare it to EQ and other past MMO's and the UI, quest system, combat, group boss fights were pretty much done already. I believe the only reason it became so mainstream was because WoW was so accessable and the lore/setting seemed to click very well with customers, hell Blizzard never even expected it to kick off so well, a lot of people claim it was a complete fluke.
Personally I don't see a point in screaming from the hilltops "This game is the greatest and anyone who disagrees is stupid". Nothing against any of you, but I seriously do not give a flying monkey if any of you like or dislike this game or any other game I enjoy. If you love it then great, I feel happy for you, but I won't let it affect how I view it in the slightest.
