The gacha system needs so much work. Uncovered my Luxurious gacha for 100 diamonds. FIVE terrible lust dusts, and 4 non-gem costing gifts. Just brutal. Shouldn't luxurious have an increased chance of memento? There's no reason to play when you're waiting on 15-20 mementos for the girls. I'm letting them all reset to 0 until I'm anywhere near completing any memento requirement.
