I'm always up for characters getting new weapons. Opens up new options for them. I mean, just look at Caeda! She was a mediocre flier at best until she got the Wing Sword. Now she ties with Elincia for the red spot on flier emblem teams, though Caeda is a more budget option and is more easily accessible for perfect IVs and higher merges. Anyway, I think Frederick and Cordelia could get Prf weapons, along with characters like Navarre and Berkut. I also want more refines for existing weapons like Eliwood's Durandal, Hector's Armads, Tana's Vidofnir and Innes's Nidhogg.
