It doesn't affect me what role they ultimately decide to have Samurai fill, I main Dragoon and I will always main Dragoon to the nigh-exclusivity of all of the other classes. No amount of tank/healer classes any MMO developer could add to their game will make me change my preference to playing a damage-dealer.

It doesn't matter the game, but so long as they use the holy trinity of tank/healer/DD, there will always be an abundance of players playing dps and a shortage of players filling the roles of tank/healer. And it always amuses me that some folks solution is "THEY NEED TO ADD MORE TANK/HEALER CLASSES THEN THERE WOULD BE MORE TANK/HEALERS PLAYER" when that has been repeatedly refuted. While there's absolutely nothing wrong with additional tank/healing classes, there will ALWAYS be a shortage of players willing to fill those roles.
