Of course Samurai was being spoken of, The Anniversary event 2 years ago had Yoshi's PC mention Red Mage and Samurai by NAME. And no, the NPC's argueing over Red/Blue doesn't count as that was ONLY in the ENG version of the game, no other region got that speech bubble. DNC was never, ever, ever mentioned, at least BLU is referred to in the ALC questline, Dancer doesn't exist anywhere aside from the sensual dancers in Ul'dah.
