Yesterday, I decided to submit a ticket to Blizzard to ask for a rollback. Indeed 5 hours later, I was happy to find the gears on my softcore characters restored, but in the process to my horror, 7 of my hardcore toons were deleted.
Among the missing were a P100 barb, P60 monk and 2 more dead P90+ toons :(( Below was the reply from Blizzard customer support:
You are receiving this message in response to the help petition which you submitted regarding a rollback.
In regards to your ticket, I am sorry to hear that you are missing characters, very sadly it appears there are no rollback points before the date we was able to select to rollback the account. So very sadly I am afraid it is not possible to select another point in the accounts history to choose.
Sorry for any inconvenience this has caused

I hope this will be a caveat for other hardcore junkies out there if you ever encounter the same situation as me.
