It has always been problem when running forgery with team. You have to get 25 kills to count to the chest, but the only killing sequences are:
First graveyard part, which many players skip without any thought cuz it's first part
Miniboss fight, where there's like 3 mobs
Last Ship sequence, where people realize "oh shit" and start farming for kills. But there are 50~ mobs in total, so it can be still not enough for everyone.
CGG has more or same grinding sequences yet has only 8 kill requirements. So decrease CUC requirement as well to 10 or something.
