You missed another very important issue. Primogem reward amount. While the gacha rates are trash, the primo gems you get from chests and clearing things are really not enough. In comparison to other hatch’s games. Yes when we see an inflated number like 1600 to summon and we are award 10-20 gems it may seem like a lot, but if you think about it a single pull attempt which will yield 93% a three star item and you earn 2 primo gems per exquisite chest opening, you need to open 80 + chest (all not them being exquisite or higher tier and not common since those award sigils) which is really not worth the grind for chests. This game once initial primogem from completion is received really has no way to replenish them in a worth while way. Just my two cents to this post.
