Something wrong with the World of Warcraft game cards

Hello everybody this is 2cool4games. Today I am going to talk about something that is wrong with the World of Warcraft game cards. Yesterday I was scratching my card then when I scratched the card it had smear marks. I almost didn't break out the combination to put the code in the box. Blizzard please change you card scratch of products because it doesn't come of? Please CEO change that product.
