Since Limsa Lominsa is short one class compared to the other starting cities i been thinking they should add Thief as a new base class there. Then as advanced jobs they could add in something like a Swashbuckler/Fencer advanced class that wields rapier/cutlass mainhand and offhand flintlock pistols for added kick. I think that would fit in quite well for themed to the city, and even out the classes per city.
