So I had 70K event currency up till today.

First I cherry picked the best stuff, and after that I blew the remaining 35K to full clear up to page.... 9 I think ?
Burned good 15 FGems to increase my storage capacity for both character and items, and yet I still have to keep 98 3* girls in the chest.

Yeah bonding crystals would sure be nice right about now
Overall > Good event, nothing to complain about. Cheers
