This time I complete 44 event quests and get around 56000~57000 pirate sliver, then I only get 1750 cards of Caspia.
Because of I'm busy for completing the Buttpass quests and have no time to open chests in Tower.
Yes I usually get the common and rare cards at the end of the event. This time my ranking dropped about 400 so I only got the common cards. I highly doubt there are so many more people playing just because of the new butt pass especially when they rolled it out so unexpectedly after a week of no event/announcement.
