This isnt really an exploit but i posted it here anyway. If you click on enter to enter wow in your character and hit alt+tab a split second after you click enter you will exit wow like a normal alt+tab and wow will still load. If you get good at this like me you can do it every time. You need to make sure that you press enter because if you dont press enter and then alt+tab you wont enter the game. Again this isnt really an exploit just a tip to get threw those boring load screens!
