Roles for Samurai, Red Mage, Dancer

[ADVSS]

I have to agree with shippuu, samurai probably would be a best bet for a tank role if we are considering whats left in the final fantasy bank of jobs, hell dragoon couldve been one too based on its armor selection but they made it straight dps. They could do this to samurai but i feel like theyd be running thin of options for even more tanks down the road. I could see it being either or honestly,but assuming this topic is these are the three assumedly given choices, i feel like samurai over dancer or redmage as a tank just feels better. Dont get me wrong ive seen good dancer tank write ups in the past even, etc.

I have to believe that if we got a cloth wearing katana class they wont name it samurai, much like astrologian pretty much being time mage wasnt simply time mage, due to the fact that time mage was more of a debuffer dps with minor healing, so they gave it some iconic skills like gravity, quick(lightspeed) and made a healer out of it. I could see a dps katana weilder being implemented but itd be called blade master, ronin, or parovir or anything but samurai.
And if they make it a tank, i mean we got abilities like mercy stroke, whose to say it couldnt get a fell cleave potency attack that procs when an enemy is low? Idea being wear the enemy down by distracting as your allies nick at it, and finish it with a well drawn attack.
