And why stop at only one server? What if I want a BC server? Or a Wrath server? Also, which version of vanilla would be the one to make? What if I liked an earlier version than the one that was created? If Blizzard were to create old servers they would have to create a server with every single patch to be fair to everyone. Do you think it's so easy now?
I have no idea why you bring up people wanting vanilla servers and GW2 not being a WoW slayer. GW2 is going to be nothing like vanilla WoW, so the original post makes no sense. It just seems like you want to just argue about something.
