Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello,

i would like to play with my girlfriend on your server. The problem is, she like to play the story in german.
We have downloades a german client. The quests are shown in english. I have read that this must be
a configuration in the server settings. French players would getting the quests in french.
My suggestion: It is possible to add the german translation on the server for players with a german client?
Thank you.
Shimanu

it'd require quite a lot of work and if you're asking me is not worth the dev's time as 99% of the german players are able to speak english quite well
