More than weapons though, I'd ask you for mechanics. What is the main damage mechanic or playstyle that Pirate would address?

We've seen them play with a combination melee and ranged caster using RDM, so you might see something similar coming out for a ranged dps using pistol and blade (there are only 2 ranged dps, but it means the Pirate would have BRD and MCH role abilities; so a lot more CC and support functionality than damage).

Otherwise, I'm flummoxed by the lore of how you distinguish the pirate PC job from every other pirate in Limsa Lominsa. Obviously the Warriors of Light are special by default, but is that really it?
