The odds are so bad. Yes, seeing any progress is nice, but if the odds are so awful, it's just super frustrating. I spend all of the event time trying to win the droppable event girls. With the days inbetween where I get to fight story girls, I barely get ANY shards. It's quite mocking. Like, you seriously think I'm going to play for a whole year to get the 30 shards I need to complete a girl from an annual event? Give me a break. There is a life to be lived, and this is a time pass. But with this kind of greedy system, it is very frustrating and makes me want to quit playing.
