Usually they won't do shit if the items get disenchanted. Like if your account gets hacked and the dude disenchants all your shit - you're fucked.
Thats not true.
If somone hacks your account and blizzard can verify its a different IP, changed pass, etc, they will restore all your items and give your account back.
Dude, one of my friends' account got hacked and they wouldn't give gold back or disenchanted items.
Then your friend already reclaimed items 4 times, waited to long to report it, didnt send noterized ID, or he didn't get hacked.
I can tell you that this is very much at your own risk. I had my account hacked by playing on a Netcafe wich for some reason allowed upto 2mb of own "Configs" wich lead to some tard isntalling keyloggers .. ANYWAYS! Reported as soon as i found out and i got my account back .. all chars itemless couss this dude dis'ed it all .. This was my first ever ticket to a GM so aint couss of that ... Maybe i just picked the Wrong GM at the Wrong day but still ... Be Carefull!
When your account gets hacked, they need you to send in ID.
If the ID matches, your account gets refunded.
You have to page a GM, if not already questioning your items. they will either say "Thank you for letting us know" or "We are already looking into it"
My gold took 2 weeks to come back, but ive known people to wait 4-5months for gear.
