NINJA and ROGUE confirmed

Personally I think Thief is a junk job anyway. Only ever used it to steal unique items from bosses in single player FF games and in FFXI all you took it along for was Treasure Hunter.

If they want to add Thief they should just make a job that stands around and does nothing but Mug or Steal until you get the rare item the boss drops and then goes and sits in the corner until the fight is over so more loot drops or use Flee when the boss is too hard to return to start of dungeon. But since almost everything in the game except for the furnishing items and mounts is in a treasure chest and not dropped by the boss, not even much point for Treasure Hunter either.

In the very first Final Fantasy, Thief upgraded into Ninja too.
