Seems like feedback wasn't taken into account at all. These events are nothing more than a gigantic waste of time because you'll make next to no progress on any of the Ninja in either of them. 180 for ONE Kisame fragment, are you actually kidding me here?

The point Rozuka is that these events don't feel very rewarding. If we were to save all of our points and buy these Fragments, it feels like we're making absolutely no progress at all and that's not a very rewarding feeling where as if we were to spend it on things like the Stamina Potions and etc then there's no chance we'll ever get the Ninjas. The point of an Event is to feel like you're being rewarded for logging in every day and doing it, and as it stands it just doesn't feel like that.
