I dont care what anyone says for me Donation tier 1 drop rate is bugged. Ive spent 4 days of the event and around 200 combativity fighting that first form , i have all the girls from that form so the only shard drops i was getting were from Hariki , and im still only at 83 shards. On orgy days usually i get 2 girls or 1 girl and 70 shards for the second , now its like i have to spend kobans to get even 1 girl. Whether its a bug or a feature , bad move either way from the devs at making it like this.
