Gosh.. just like the server failure the launch day of D3.... They need to get on board like they are for WoW...if you are hacked they replace all items and gold. EVEN BoA gear can be replaced! DH got hacked a couple of months ago and it took the GM who responded to his case less than 3 hours to get it all back to him.
I guess they feel that Diablo is not as important because no one has to pay for memberships.. but still.. you create it.. fix it! People spent loads of money for the game in general.. they make bank
