Blizzard only helps to an extent. They do not or will not replace everything to exactly what you had before you were hacked. And now if your hacked the first time they will fix what they are willing to fix after that if you don't have there authenticator they wont fix it.

Yes I linked my 4 accounts and I love the easy access. I do NOT like the idea if I do ever get hacked that they can wipe out all 60+ toons that I have. And then trying to get bliz to replace all the items on all the accounts will be like pulling teeth. Because they will probably scream murder and only fix one account. Or half ass fix the others. But blizzard is going to eventually make us do it so might as well get it over with. I'll just have to keep spaming the page for the authenticator and maybe get to finally purchase one.
