I think a mangled version of Everquest would make an interesting server. Like someone said, restricting the level cap for awhile might be funny - how many level 10s do you need to take down Lord Pickclaw?
For myself, I'm not looking for a "classic" server and I have no illusions about what a new server would be (not that "new") but still, I loved the older content of EQ and I would try and be present every time they set one up. Even if it's wrong or everyone isn't happy, they can always do another (and I'd be there for that one too).
Sadly, a lot of the qualities that make Everquest (new and old) so great have never really been duplicated by any other game. You'll be hard pressed to find a game now that has character development as in depth and personal as the AA system was (and still is?) not to mention the spells, keys, skills, gear, augments, and just plain experience. Also the fun of searching new zones, finding Named and their placeholders, learning the pulling patterns (for pac and mez impaired like myself) and just being dependant on your friends for help is something of the past, from what I can tell. Where can we find these things but Everquest?
Anyways, I can't wait to see a new server, whenever it might come, and I'll certainly be there with all of my friends.
