First: Get a sense of humour. Just because you don't think it's funny doesn't mean it really isn't funny.
Second: It's only obvious to most of us because we've been playing for a long time and have been looking out for the new jokes by Blizzard. I remember being fooled by the insane list of requirements before BT would be open and you would be attuned, since then I'm always looking forward to Blizz their jokes. But not everybody knows this and tons of people where fooled by this years jokes.
Third: It's their money, they can do whatever they want with it since you paid for something your going to use next month. Paying each month doesn't mean you got to say what they should do with it, if the game changes and you don't agree you can't ask your money back.
