How many raids did warfronts cost us?
They shouldn't have been exclusively PvP.
They however should have a PvP mode.
Warfronts were a cheap way to add content. They took MoP scenarios and made it larger is all...warfronts take *substantilly* less effort to build and maintain than the previous PvP zones (this is one of the many ways Blizz was able to report such a massive cut in costs as reported in their financials yesterday).
