It was the opportunity for a large number of players to get Halloween Juliette. The fact that you weren't lucky enough to drop her doesn't necessarily mean their implementation was half-arsed.
Also, they focus on each month main event. These "revival" event are just bonus: an apportunity for players to acquire girls they missed in the past and for Kinkoid to get a bit more money. Complaining because we got bonus and additional opportunities seems not reasonnable...
You're getting ridiculous here...
