Because you have to earn the right to bypass how they want you to see any new content they created. If they added that bullshit then once you died a few times or read a guide on how to avoid being knocked out of the sky then you'd just skip over monsters and the world wouldn't feel as dangerous. Then you'd have to deal with that shit for the rest of the expansion or you'd beg them to remove it somehow at some point cause it would just feel stupid. Alternatively you could wait until the first patch to play WoD and not wear those grumpy pants anymore if you feel this strongly about it?
