Are people really still saying Thief can't happen in XIV, when the Bard we have is... Well, not Bard? Three Songs doesn't make a Bard, it makes it a DPS with Songs. Thief would be exactly the same, for better or for worse.

Just mix it with Chemist (Rikku says hi) so we can have a proper Mix system in the game, because if we get Chemist it'll work like Archer, having a magically infinite pool of potions. Mix it with Thief though? Steal steals reagents from enemies, Mix mixes them together and then you use them. Then just throw in the enmity management XI tried for and you can easily go about adding new abilities, just like Bard they wouldn't all have to fit the Job either, unless you're telling me Rain of Death is a spoony ability?

Instead of saying "Thief wont happen", say "I can't imagine Thief happening", because that's what you really mean.
