I was questing while someone asked about playing with German client. I don't speak German but I looked into it and found a torrent made by another server.
For those interested, you can follow the instructions here.

Once you have the client downloaded, change realmlist.wtf to:
Code:
SET REALMLIST logon.warmane.com
SET PATCHLIST 127.0.0.1
Disclaimer: I have no intention of promoting another server. This information is being provided to help German players play with a native client.
