Hello, I'm now gonna show you how to get premade characters to the PTR server as a EU region player.
Start of by log in to you battle.net account on Battle.net.
When you are logged in to your account press "Manage Games" then on "Buy Digital Games"
When you are on the "Buy Digital Games" site in the right corner you will see a small "box" that says "Game Region". Press that and change it to North America.
After you are done with that go back to your account summary and add a 10 day wow trial to your account. (Make sure it says Americas & Oceania under the link as region)
When the trial is added to the account just go to http://worldofwarcraft.com/ptr and go to "Copy a Character" as usual and choose a premade character and then just login to the PTR .
