if u were to buy a computer just to see that within 6 months the company will offer a pc twice as fast and twice as cheaper then u would complain for sure. this is pure deceiving!
if u think u shouldn't complain then u have a bad perception of reality (or economy).
i payed 5$ to finish a quest that gave me 1000atk item. today these items are given like hot pretzels, so yes - i want to protest
