It is concerning me a bit... but perhaps it has always beeen this way. So far there has been quite a lot of information on many things that WoD will bring to the game. They even talked about many main changes to PvP etc etc, but I haven't seen a single clue about new battlegrounds.
For some reason I'm affraid they aren't implementing any. Is it always like this for every new expansion? (as in.. information about new battlegrounds and arena maps only showing up very late) or are my concerns justified?
