I do agree that the emotes are being sold for more than they should. For example, i bought the witcher dlc for 8 euro. That gave me about 15 hours worth of exploration and a excellent new story. Destiny giving me the option to buy a 20 second animation for the same price, would seem very overpriced to me. I just can't really see why people would spent their money on it. I actually kept wondering that when some guy in my fireteam did the thriller dance. You shouldn't judge them for it though, it's theirs to spend.
