Unless they make Samurai different from the tanks we currently have, I probably won't be that interested in it. Just another likely-to-be two-handed sword wielder. If they give it some unique mechanics and maybe even have it use a naginata (or anything that isn't a sword) instead of a katana, I would actually try out tanking in Stormblood. :P

I'm still wishing for Dancer, but everything seems to be pointing towards Samurai.
