Before, if you didn't have latest the WoW expansion, there would be a little panel with options such as buying an expansion or trying a trial of it for 10 days inside your account.
Now it's gone. All I see is this Diablo 3 offer, but a "Free trial" link appeared in the list of things you can do with your account (when you click on your WoW in the list of games). The problem is that it doesn't work. It links to nothing. When you press it nothing happens.
Also, can't you usually get 7 days free for WoW's birthday? I thought that was today, but I can't find a link for it.
EDIT: I have starter edition and BC's trial would reset after some time, so I was able to level to 70 like that.
