Buu, I agree with Chthugha that it's quite hard to understand you, but I think what you're saying is this: The patch notes stated that they'd change the attraction system, to make it easier to complete girls, yet, out of fifty fights, you only got 2 points, instead of the 15 to 20 that you're used to.
First of all, I'm sorry for your bad luck. However, the change to the system is not an overall drop rate increase. All the change does, is that when you get a drop for one of the boss' non-event girls, it skews the chances towards getting a drop you already have. So if, for example, at Dark Lord, you had 20 points for Sheherezamond, 5 for Kimie, and none for Arcana, when you'd get an affection drop, the chances of it being Sheherezamond or Kimie would be bigger than the chance of it being Arcana. However, the drop rate itself did not change. And event girls don't count, so Keeka doesn't get the changed rate either.
Does that clarify the issue?
