I was sceptical, when they introduced Surprise Chocolate, but now I don't want, for the life of me, go back to the previous system.
Anyone remember the first event, which was comprised of 16 half-day segments, each allowing you to farm for only one out of 8 types of Chocolate-coins and you needed about 100 or 200 for a single Valentine CE?
Additionally, each Valentine CE only boosted a single type of coin, depending on the servant's class. This was the only time, I regularly changed my showcase lineup to help players with each segment.
