Dongrade probliems

I've Downgraded my druid from cata but once i login it shows me 'login fail' but what i mean is my druid was troll

so i think bcuz it was troll it wont work?

Greetings

Troll druid didn't exist in wotlk, same for goblin or worgen. They said that they wiill add a feature which allows you the downgrading. The feature creates you a tauren druid in your case, and you can later chose a new appearance. Write a mail to [email protected].
