1) Open up your WTF folder in your WoW folder.
2) Open up Launcher.WTF in notepad.
SET accountType "LK"
SET accountType "CT"
4) Open up Config.wtf in Notepad.
SET accounttype "LK"
SET accounttype "CT"
6) Start downloading the 300mb update by starting Launcher.exe
Found this on some other forum, hope this might help (afaik this isnt against the TOS, and it might give you a small head start on your journey to 85 when cata hits)
+rep if it helped
basically this will make my dl 300 mb quicker when I get the game ?
Nice but will I still be able to play after downloading it ?
when you log in with your accunt its set back to LK, unless you have a cata acc tho. nothing to be worried about.
