On the other hand, some people are reaching the point where they have nothing left in their teams to upgrade. I have just one girl in my teams who has any room for manyu improvement...every single other team member is evolved and fully upgraded, so now I'm going back to the ones that don't make the cut for the big four teams in case they implement nationality battles (which would invalidate the concept of 'never going to use' girls). Of course I'm saving the appropriate manyus for the event girl we're getting in a few days, but the other colors need to be used somehow.
