i have asked a german gm (and also in the german wow forums) but they don't know why it was changed, but they said it's not a bug.
can anyone ask in the US wow forums please? in my opinion the europe gm's are far far far faaaaaar away from any kind of information about ingame changes from the US game developers......
maybe someone can create a thread on the us suggestions forum or in the customer service forum (i dont think that my europe wow account will work for the us forums).
