I have gotten a Peistskin map every single day since 2.1 for a total of 244 maps not including over 20 maps a fiend gave me and I didn't get a blue bird in any of them, while a friend of mine gets his blue bird the day 2.1 came out and he gets a second one later. I feel like the blue birds drop rate should be increased at this point because it is several months old, I am not willing to pay 2 million gil for a minion /rant off.
