Samurai will be tank or dps that we know. What about how it plays, shouldn't that be more concerning then the role? If samurai was dps I think it would allow SE to be more innovative in making another melee dps. (if they take the opportunity). If they draw ideas from the samurai in tactics and the tp techs from cyan in ff6 add "new mechanics" to differentiate itself from the other melee I think it could be interesting to play. Have it be fun to play and who cares if "samurai class attacks monster from the behind".
