@JeremyECrawford with the official release of samurai, can we expect a ninja for maybe rogues or even an additional class option? I've got ideas if you're hiring 😉

Monks who follow the Way of Shadow are often called ninjas (see PH, 80). #DnD https://t.co/tGlkPdzBMC

And, to be fair, you could play a "ninja" (a spy, covert agent, shinobi-no-mono) as pretty much any class. Same with samurai (archers, swordsmen, diplomats?) – I feel the the "official" subclasses aren't that important if you want to put your own twist on a character.

I encourage players to reskin classes/subclasses/backgrounds liberally. Take the class/subclass/background that fits the function you want for a character, and then tell your character's unique story. #DnD https://t.co/uDkbu317gT
