New Job Thief Concept

[Shurrikhan]

Unfortunately SE already said they would never have any Thief class in FFXIV because it just wouldn't fit into the lore to have a sanctioned guild of thieves.

In all fairness, why should it have to be sanctioned? The original Marauder's guild wasn't. It was a pirate ship. Then again, Yoshida somehow felt the need to replace it, too, just to fill the space of the then-Musketeer guild and ensure there'd be no Gunner class, only to make Machinist, essentially a gunner job, one version later.
