My girlfriend has been leveling a character on my account until she gets a computer that can run the game. Is there any way to transfer her character to her new account, or will she just have to start over? (Ex: in WoW, you could branch an account off of yours and transfer your characters between accounts)
I don't think you can and it probably isn't a feature in the near future.
I started a trial account for my girlfriend to play on until she was able to get an account... I recommend the same plan, mate.
