Please bring back the old arena battle. I wanna use all the birds in an arena at the same time. It's really hard to rank up when birds, especially the extra ones, aren't that great in terms of bird power. Also, when an event comes where birds can increase their power upon getting their special hats, only red or blue can be usually upgraded since their hats are the first ones to get. Please shuffle the bird hats and make Terrence's, Bomb's, Silver's/Matilda's hat first to obtain. This is a plea.
