Nostalrius Begins - Quality wow vanilla realm (1.12)

Are there any class guides out there that i dont know of like you see a lot of them for retail wow about how people tell you how to play that class. Would be a cool idea to see people make guides for their classes. Do they exist?

There's alot of guides on other private server forums. Even old guides from retail vanilla can be found here and there. With a little bit of googling skills.
