Don't bother checking in every hour on the half to get more Brewfest Prize Tickets, because the Dark Iron Dwarves aren't showing up at Brewfest, and Bliz still doesn't know what to do with them.
The big B is reviewing the mechanics of the festival's prizing scheme and hasn't come to a conclusion as to how the Dwarf attacks should apply, so the whole thing has been put on hold until further notice.
Were people getting too many tickets? Maybe. Was the event causing network traffic havok? Who knows. But whatever be the case, we'll have to be a bit more careful in our collection of 600 tickets. I don't think we'll have a problem or anything, but with everything that has happened, who knows what'll go down next?
Oh, and if you think Blizzard would be kind enough to extend Brewfest to help matters out a bit, think again.
