If it were possible for you to buy a lifetime WoW subscription, would you buy one?
Lets say they set the price at $500 USD, and you never had to pay a monthly fee again, and you always had access to your account to log in and play on your servers. (granted that you did not cheat / exploit / go against ToS). All you would have to do is purchase the expansions whenever they came out to access the new content.
Would you be willing to drop the dough and buy one? Why or why not?
