We knew that the hero was not in the gold chests. This was verified by the game sage. There was discussions here and in VIP and other chats early yesterday that pointed out that the hero was not available.
The primary focus of the discussions yesterday were that Gree would refund chests so to cheat and use your chests now.
I personally did not use gold chests, my own moral code wouldn't let me.
What is frustrating is that you have rewarded the players who took advantage of the situation or cheated you, rather than those who didn't.
