Cancel wrath of lich king 10 day trial

Hello GM:
Sorry to trouble you. I want to reflect something, I think you will interested in this thing. I have a Chinese friend, he used be a gold maker, I know Chinese farmer how to make gold. 90% Chinese farmer use the third part software farm ore in wintergrasp or sholazar basin. They aways use wrath of lich king 10 day trial, if you cancel wrath of lich king 10 day trial, I think Chinese will not use software farm ore in wintergrasp. Because cost high. They could not buy wrath of lich king, because their account will be closed by you in 7 days, they will not buy wrath of lich king, it's not worth. If you cancel wrath of lich king 10 day trial, Chinese will not farm ore in wintergrasp or sholazar basin. So game will balance. You could try cancel wrath of lich king 10 day trial 7 day, you will found Chinese will not use software farm ore in wintergrasp. I hope you will cancel wrath of lich king 10 day trial, because our want to play game in a balance game environment, thanks!
