I'm at the point where i'm evolving and giving affection items to 2* girls because most others are already done or waiting for their colour manyu.

As of currently i do not use bronzies anymore but i had them for a long time and Hydrangea is one hell of a bronze along with many others. Frankly, there is nothing bad with evolving 3*s because they pack a decent punch and you can clear this whole bloody game with a team of 3*s.
