Historically Accurate Samurai as a Job Class.

A historic-accurate Samurai job will utilize spears and bows as the main weapons, with Katanas being the last resort.
From what I know, Samurais would use any weapon that gives them an advantage in battle, and if they unsheathed the Katana then that means they're ready to fight until death.

Tbh Samurai may as well use guns if this is the goal.
As opposed to what a lot of people believe, Samurai had no issues using firearms.
