im honestly surprised people thought it would be the same price as a sub or even lower. im not a tin foil hat conspiracy theorists but blizz isnt going to implement something that has the possibility of them actually losing money.
theres a chance the subs might drop a little due to people using their in game gold to buy the tokens but for every sub lost because of that someone is spending $20 for it to happen. they stand to actually make more money which is the goal of the business.
