Rather than being angry about not getting certain ninjas from events that relies on luck, maybe you should start spending it on events you know what you are going to get. Worry about your progress rather than someone else. Since we get these types of posts every time an RNG event comes by, I figured people would get the message to stop doing them with the intention of getting the 80 frag ninjas. If they won't stop, then don't complain since its based on luck.
