Drop rates are literal poop. Pulled about 100 times, which would have guaranteed a 5 star according to any drop rate, even if it was 1%. Didn't get a single one. There is no more story after you're done. They keep adding side quests and dungeons that aren't helpful. As a gacha game, it should be easier to get 5 star characters. This is an absolutely horrible game, not to mention storage (about 2.5-3G). AND THE GEM UPGRADE IS BY CHANCE. THAT IRKS ME THE MOST.
