One of the primary advantages of another role (and the levers it brings) is that we can take another look at non-damage utility. It's hard to justify Monk's damage and mantra when paired against Samurai, or Black Mage and nothing paired against other mages, but the addition of their own role to properly reflect their "selfish" nature means we can more readily define the jobs of both roles and improve their unique non-offensive capabilities.

For example, where a Monk increases party healing, a Dragoon might increase party movement speed, and a Ninja could decoy jutsu someone to reduce the damage they take.

The Samurai, being the selfish jerk he is, could have a notably improved Third Eye / Merciful Eyes - reducing the burden of single healing on them.

You don't always need the party healing, the party movement, or the mitigation (The ole "Any mitigation that doesn't save a GCD isn't good mitigation"), and you won't always need Samurai's self sufficiency, but each of them would have a place depending on the mechanics of the encounter and needs of the group.
