I liked this event. The 'collect so many cards of this scarcity' is more doable than before due to the regenerations in the dungeons, and I was able to buy five girls, one of them being an epic girl. I would like it if buying the girls in the bottom row, where there are so many rare, epic, common, etc for so much copper, would count towards these events, as it would allow the gameplay to go faster. That would have allowed me to get more girls. Overall, I think these kinds of events are great, and I like how you all figured out how to help out those of us who missed some of the events in the past, or could not get girls due to the above types of challenges when they were impossible. I think this game will be great once all of the bugs are ironed out.
You are right about the epic chest thing. I had to wait two days (and it seems I was lucky), and I had no time for the collect 60 epic cards quest. Relying on chance only for a quest does not make for a good game.
I still liked this quest because I got two Aztecs, a couple of those Hell's Angels (one was an epic girl), and I got one of those black cougars as well. I had one Aztec from the gem chest in the shop area before, but she was just the one who does the power of nature, and she is still far too weak to actually use. I have been using the earth girls from the dungeon who have been getting very strong over the course of this game due to level ups.
