I honestly really hate the way dancers are distributed in this game, tbh.
Heroes, FE7, and Fates get all the amazing premium dancers because of the fairies, Ninian, and Azura. Who yes, are important, but it certainly doesn't help me with limited battles that aren't one of those games.
3H is pretty well off on dancers because Dorothea's later two alts are at least good. Genealogy/Thracia doesn't really have a single standout dancer like Ninian and Azura, but the sheer quantity of dancers is a lot. (They also have Duo Sigurd.) PoR shares Harmonic Azura at least, but RD only has the herons and the very old Hoshidan Festival Micaiah and Elincia. SoV only has the rather old Soiree Berkut and Rinea. Binding Blade has the two Larums (neither of whom have a prf) and Sacred Stones only has Tethys. Awakening has four very old dancers, the most recent of which is that flying Olivia who is also the only one with a prf, and I swear Archanea still only has Phina. EDIT: Oh, and Engage only has Harvest Seadall.
The distribution of dancers is plain embarrassing.
