Nehthaera today wanted to let a lot of the naysayers out there know a thing or two about their April Fool's jokes and the issues with the servers. She tells us the obvious, more or less: the people who do the April Fool's work are completely separate from the people that do the server and development work.
So these elaborate and well done jokes have exactly zero impact on the servers. They don't have anything to do with maintenance, with patch 2.4, or with Wrath of the Lich King (well, unless you actually believe there'll be a bard class). This means they could have done nothing for April Fool's, and things still would have been as difficult as they were yesterday.
I want to give Nethaera two thumbs up for her post. I really enjoy it lately when GMs and CMs lay the smack down about issues like this, especially to whiney forum posters.
