So apparently a working Monster Builder (by working I mean "that actually builds monsters") is a pretty damn low priority, since it will have been whacked for nearly a year by the time they get it working again.
Very disappointing.
That's because those people who cared enough to cancel their subscription over it have already done so. Everybody else has the kept their subscription or re-upped despite the fact the MB doesn't match the offline's functionality. So there is no rush from their point of view. Better to keep up with their state goals of instant inclusion upon a book's release (along with small steps in getting the build aspects of the MB up-to-speed)... than to not succeed in either of those goals in a misguided attempt to put a rush on the MB build additions (considering they probably have no idea how long the actual programming will take to get everything into the online that the offline had).
