, give it a decade to a decade and a half and if people haven't lost interest in FE and if Nintendo hasn't gone bankrupt due to more Wii U-esque ideas and if a Radiant Dawn remake happens to be made around the same time as a Smash game, there's the slightest possible chance Micaiah might be considered for a playable character. Ya know, basically going after a 1% crit with a 1% hit chance but it's there.
As for the berserk thing, I'm thinking it wouldn't have range like berserk staves actually have since it's just a medallion and as I said, Mist has frail defense so it'd mostly be useful against mages. Admittedly, I actually haven't played any FE games with berserk staves (got halfway through Rekka no Ken, did Erika's story in SS, beat PoR, RD, SD, Awakening, Fates Birthright and have been on the last 2 chapters of Fates Conquest since the fall) so I don't know how OP berserk would truly be.
