If you buy a dollar store item, and you open the packaging and it has two of what you bought, do you go back and give them back one?
If you buy a candy bar from a vending machine, and two drop, do you send it back to the company the same way you'd have to call them and get you to refund you a dollar if none dropped?
I didn't use the exploit, but if people had offered on my server I would've. Because Bioware decided not to do an update for 5-6 weeks after the expansion dropped. Release your **** right, or fix it as soon as you know there's a problem.
