i have idea for next expansion (a. k. what to expect next):
they should just implement some cliff where characters can jump down to death (fun part), and some ladders for casuals, and stairs for elite players...to climb back up (grinding) after they have jumped dead 1000 times, they get an token and 100 000 times, wallmart coupon (reward). token makes you able to take elevator once and walmart coupon gives "made in china", save-the-pacific-from-trash-mug, made from toxic plastic or flammable rubber thing what you can put under beer glass, and you see "blizzard" hologram there when looking through emptied class.
all should be connected to twitter and facebook, of cource, and you can put your followers jump to death with mobile phone app.
