You deserve it.
You've allowed them to sell basically everything in this game, a game which has a monthly fee, in which nothing, should at all be for sale. Soon you'll probably have to pay money to use your Hearthstone or something. You sat back ignorantly and allowed all this crap to happen.
Enjoy it.
I guarantee you, 100% in the next year, you'll be buying gear from the in-game store. Why? Because they know they can get away with it.
