Re-reading it I think that's what was being said I just misread it - sorry was late in the evening got me confussed

Actually, even if it change nothing at 100% affection, it's still better to evolve a girl with 100% affection than with 0%. When you evolve a girl, she is back to lvl 1 and get lower stats than her lvl50/60 pre-evolved form. But if she is 100% affection when she evolves, the double affection bonus compensate the stats loss and she will have almost the same stats than her lvlmax non evolved form. It really matters u til you get enough good evolved girls to make solid squads.

Ok,
Thanks for the awnswers.
It'll be just a matter of luck with Manyus and Dragons then (not receiving only lvl 1 dragons after doing the 80 stamina map would help a lot, but anyway haha)
