For some reason, Blizz have decided only to open up the PTR to the Us at the moment, however this little trick will allow you to get onto the PTR now using your EU account albeit with a premade character. Good if you can wait to test out the new 5 mans and other features.
under > YOUR GAME ACCOUNTS
1) click Buy Digital Games LINK (don't worry no money is going to be used)
2) in the top right click Game Region and change it to North America.
3) Go back to to YOUR GAME ACCOUNTS
4) Under all your accounts you should now have add WoW starter World of Warcraft®
Americas & Oceania (US)
5) Go to http://www.worldofwarcraft.com/charc...cter-copy.html
5.A) if it says "There are no World of Warcraft Game Licenses attached to this Battle.Net Account" then you did not add the usa starter accont so try reading 1-5 agean.
6) Copy a Premade Character
7) Pick a Character
pick the EU realm on the list brill (eu)
9) have fun with your 378 geared Characters!
Voilla, log into PTR
you may have to go back into Game Region and swap back to EU in order to transfer your character when it does become available for EU
