Drop Rate gives me headaches, I tried to get an event girl, farmed Edwarda for 7 days, and got one of her regular girls. The new event started today, and I farmed Darklord a little, then he dropped the event girl, switched to the second event location, attacked, and I was done with farming.

Well this is nice, now I can go back to finalmec and get some extra cash, sometimes things do work out for you.
