Best event ever!
Spent my entire Koban savings of 9000 on refreshes for around 1000 battles total, and I have absolutely nothing to show for it!
Now any love or addiction I had for the game is gone so I can finally quit. It would take compensation of my kobans refunded and getting to girl to come back. Offering a limited unit for 4 days with impossible odds to pull is clearly a scam. Clearly event's purpose was so we could burn all our kobans and be forced to buy the monthly card, which without I can't even claim my harem revenue without a headache due to no kobans left.
