It’s the stupidest thing a game can have. It deflates the players enthusiasm to want to keep playing knowing that its totally dependent on luck. MAKE THE PLAYER EARN THE REWARD NOT GRIND THE SHIT OUT OF IT ONLY TO KEEP COMING UP SHORT EVERY TIME. For a game to maintain a players interest there has to be a sense of progression. Please require that ANY quest do not have a 100% RNG element to it.
