I'm at the exact same situation as you. So I feel you brother.
In my case it's just the opposite faction that gained valor in a discourageing way.
Unfortunately I have entered a prepaid card so I have 69 days left. Something happened though, I started playing abit today after feeling bummed out since patchday. But yeah...
Atleast now I won't ever spend exaggerated amount of time on something in swtor, since Bioware apparantly didn't listen to PTR or are able to think ahead, so you never know when something YOU find worth ALOT of your time, is going to be able to get in few hours.
And rollback? After the credix exploit and we didn't see a rollback, I really didn't expect it in this case either.
The next 69 days will determine my future in swtor. Bioware, you have lost my trust in you and SWTOR after this incident. I will however as planned, pick up a 2nd hand copy of ME3.
