Honestly I've always had the classic feeling that classic was Velious OR Luclin. I'd play on a server that was up to PoP but no further and it wouldn't be my first choice - only because of the raids - everything else about PoP was stupid.
Flagging/Keying, PoK, faction being meaningless, excessive AAs... imo Luclin AAs were perfect (Luclin did have other problems though), enough to finally flesh out class roles but PoP AAs were just hamster wheeling. LDoN was even worse when it came to this. I remember it being billed as an expansion for casual players to get near raid quality items which they did, but it also added "needed" raid items for raiders. Aggro augments and armor augments for example, and it was just running the same crap over and over for those. The dungeons weren't even interesting either, killing orcs after I've been killing giants/dragons/gods... wtf. If LDoN had been an expansion like LoY with just content for lowbies/casuals/visual stuff it would have been ok, but the rest yuck. I guess you didn't really have to play it, and in fact I barely did
