1) It's Alim who makes these units' 7* forms and Gumi just transfers them onto the GL server. 2) Alim announced that Arus and co. were the last Legacy Units, so Fiora getting a 7* is unlikely now. But I think they're going to start giving old units Omni Evolutions though, and Fiora might be one of them.
