An easy way of skipping to other stuff when Warcarft is loading is basically before you log off or exit game click Window Mode (maximize) in Video Vettings. Then next time you log on you can switch screen while Warcraft loads.
Simple and proberly posted before. Works for battleground entry screens and possibly instance ones too. But I figure it will be used less since I normally switch back to normal view anyway once i'm in-game and playing.
