Copying pre-made characters is "disabled" on the EU Beta realms. Trying to click the button on the beta account pages gets you "This feature is currently disabled" which has been there since the launch of beta for EU testers. However it can easily be bypassed so that you can copy pre-made level 80 characters to your beta account. Just to clarify, this is not an ingame exploit but rather a sort of exploit of the beta account pages allowing EU beta accounts to copy pre-made level 80 characters to their beta accounts. Something that they otherwise cant.
First logon to the beta account pages so that you are logged in.

Secondly open notepad and paste this in
Save it as whatever.htm and open it in the same browser as you logged in to your beta pages with. Click the button. You can now chose between loads of premade characters to copy to your eu beta account. Enjoy.<form action="https://beta.wow-europe.com/game/character-copy.html?ticket=ST-84570-jFwNOE3eOHtyFbR2cTLP">
