Well, if Samurai is being added in Stormblood, and SE follows the standard of adding 1 of each role as a new job, and with RDM being revealed and shown to us as a DPS, then Samurai could either be a tank, a healer, or not included in this expansion. I can't say I would want it to be a Healer as I'm not sure that makes sense. It could be a tank, but that does give us 3 sword tanks. It could also be saved for a future expansion, but would that annoy people wanting to play Samurai really badly?

It feels like, "Tank, or bust," at this point.
