What i do think we should do is draw from experiences of the way AV was or should be and ask for a new battle ground.
A new 40 vs 40 raid style battle ground. Come up with what you would like to see and suggest it.
Could be something like, 40 Alliance and 40 Horde players are trying to recapture a lost Pandarian Temple. Each side has to establish a foot hold and try to hold the other faction off. At the same time, they have to try to capture the temple and defeat a raid style boss before the other side does it.
Design an old AV style battle around a new story.
