And can you imagine the uproar on these and the Blizz forums if they didn't tell anyone and just dropped it in beta? Just like they have done with certain aspects of the game before..
With how you and some others are reacting to this then that is exactly what they should of done, not tell anyone and just drop it like a bombshell in Beta.. People complain that Blizzard don't communicate with the community..
And with how this thread is turning out only solidifies why Blizzard are hesitant with talking to the community..
