Well the problem with normal world girls being slower is its worst for newer players as that means when an event start(which is like every 1-4 non event days wth) they will always be at a disadvantage as normal world girls can steal affection point gain from event girls. Example last epic days Sifra(expert) would be harder to get if you had the 3 plain ninja girls because they(all 1-3 of them) were still able to gain affection. Thus can ruin a free or a saving players epic days girl hunt or any event girl hunt if your newer. The only upside to the new system is a progress bar and when all things are considered its not a real good trade off.
