I used to be able to almost complete the Japan event, but they've rebalanced it in such a way that I spent 48 hours stuck on rank 20/25, I quit mid event, and I still finished in the top 10% of participants, so clearly I'm not alone. In many idle games, as you progress in the main game and it gets grindy, the events provide the entertainment. I really have enjoyed the events, but this broke me, I'm done with this game.
