You don't see anything wrong with this? How about diluting the playerbase further into little expansion servers? And you cannot reset or shutdown willy nilly when there are still players that want to play that particular time period.
I thought vanilla fanboys hated everything about the later expansions and their QOL changes? And it's rather funny looking at your response and then looking at your signature.
To ask for TBC/Wrath/etc is to basically ask for retail all over again.
