I don't like he drop rates either. In one event I could drop 300-350 kobans after saving up and get most, if not all the girls. They need a bigger drop rate or drop amount. 8-10 min. And I don't much like how anything else is being run either. They need to go back to dropping daily stuff at 11pm instead of 12 am. (Eastern time). Plus they need to do a better job of lining people up in the arena. I have 182k for an ego (that's with out boosters) and I amxed out a single stat and they have me constantly up against 95-220k. Seriously? lol.
