I cannot explain in words how much of my faith in Blizzard has been restored by this. I truly thought since this had been a part of their planning for RealID, that they would not change their minds, despite the community outcry.
I hope some of the people who have canceled their subscriptions because of this will come back.
I was seriously in tears today reading posts from well respected members of the community who were leaving.
The heartbreak is over. Come back home.
