You are confusing fans with die-hard fans. Highwind is 'famous' because he was a main character in FF4 and the first dragoon, just like Cecil, Celes or Terra are famous. But does it mean that every highwind knows by heart EVERYTHING about ALL games in the franchise? I played FF6 but didn't know that Rio Blade was a move from there (I believe you said that, right? Can't remember right now). I consider myself a fan of the franchise, as do other people, but doesn't mean we KNOW everything bout everything. Yoshi is already doing lots of fan service (LB names, golden saucer, etc). Simply renaming a move won't make people go "OMG, IM SO GONNA PLAY THAT CLASS NOW"
