Donatien - been farming for
Lola since the world has opened. Must have fought him at least 3k times already since his last drop. (3-4 months?)
Personally I don't mind, since I have all the girls from previous bosses given I fight them 30-40 times a day. Now skipping Lola nad Sylvanus gals to farm the ladies of the new world which has just opened.
I don't mind the low drop of the World girls but of those from events - in every other game on Nutaku, you are rewarded with an event girl (FKG, MWA) whose strength is based on your effort. In this game on the other hand, you can put as much effort as you want and still get no drop. (I had to use all my saved Kobans - about 750 - on one of the Spring girls)
Nevertheless I still really enjoy this game, and "Harem Heroes" is one of the only three games I play on Nutaku. Keep up the good work.
