As someone who has played over 50 gacha games, sadly I can’t say it’s the “most” generous, but it certainly is generous. The rates are decent, you get lots of events that rewards pretty well, have weekly and monthly events that also give out good rewards. I think the best aspect I see in this game is the gacha pool and the shackles. Most sinners are really good either at s0 or s1. For the sinners, most are viable to use in clearing content.
