I do not understand why everyone is so annoyed when asked about battle pets. Whats wrong about being interested and thinking it's gotta be fun?
"It's not the most important thing in WoW". Oh, so serious? -.-
It did not work on an other private server I have been, too. I don't know if that's because no one cares about it or because it's hard to provide.
I would also be happy about an answer/statement. :) There seem to be not many player to whom it's important, so of course it's not the first point on the list. I understand that.
