I hope you enjoy your experience of Classic since you never got to play it live back then, as is the case for a lot probably.
When the rose tinted goggles lose their shade and a lot of people quit in under 6 months, the live game you Classic people trashed on for years will still be there for you.
I feel as though I'm in the minority of people who played Vanilla and don't think it's the second coming of Christ or something. A lot of my experiences were NOT fun or enjoyable. Maybe it was being a tank, maybe it was because it was my first MMO, who knows.
