Warcraft 4? I believe the beta isn't even released? Are you talking about a mod that someone did? Or are you talking about the "Warcraft 4 Edge of Eternity" being made in this forums? If so, the beta isn't released yet.
Warcraft 4 Edge of Eternity
That isn't an official Warcraft 4 released by Blizzard. It's a modification of Warcraft 3 done by professionals. Well, the beta isn't released yet. It's just the client launcher is released. Just wait for more updates in the future.
We're professionals? Huh.
The definition of a professional is someone who lives of it.
