Bigcat, there's a problem with your idea of a clean server. For one, the idea of defiant gear. The classic people want to go back to the days where +15 to any stat on gear was UBER and that +50-70hp with no other stats at all was OMG <drool>. The whole idea would be to go back to Naggy raids with only the gear that was available at that time. Or raiding Trakanon with only gear available in Kunark. Defiant gear would really screw things up I'm thinking. The challenge is part of the reason to do this, or at least it would be for me. And it wouldnt be progression server because they want to stay in the orginal content or kunark.
Here's my pipe dream for all those classic people out there. And this is probably worse than their idea for the devs

Anyway, my idea would be 1 progression track per guild. What does that mean? Well, your GUILD would have to unlock the raids and zones in order to access the gear and zones. This would be exactly like a progression server, but my big problem was that things were unlocked too quick for my pace. And what was the point of raiding NToV if the top guild just unlocked PoP for everyone? You'd be able to transfer up guilds (like going from a guild at kunark to PoP) but not back down. Or maybe you can, but when you get the tag the zones will be locked and the gear will not have any stats for you (so you'd have to unequip it). That way i can be in a guild that is going at the pace that i want without having things opened automatically because of the 1 hardcore guild. And the people who want to stay in the classic only, they could as long as they dont finish off the expansion. In theory, you could stay in whatever period of time you liked best. I'm a fan of PoP, so if I could, i'd stay there. <shrugs> its a pipe dream and would be insanely hard to implement i think. And while I'm at it, I still want my damn TA
