The really amusing thing is that the players haven't learned to roll with stuff that happens. Even after seven years of WoW trying to get it right (and still failing, might as well not even sign on during patches), people expect it to be different. Maybe people should learn from their frustration and take a chill pill when this stuff is bound to creep up.
Unforeseeable crap happens. It happens offline, too, but you're likely too glued to your computer to realize it. It's like.. an unexpected rain! Do you fire the weatherman when mother nature decides it's time to shower instead of giving you the predicted sun? Nope!
