Paladin needs greater damage mitigation. Anyone who believes otherwise has no idea what they're talking about. It doesn't fix the enmity issue because that's what it's not trying to fix. It's trying to fix the "Paladin has less survivability than Warrior" issue. If Paladin could mitigate more damage, it would be the safe tanking choice and as Noctis has said a hundred times or more now, the party could decide to go with a 1 White Mage build if they wanted to.

Does Paladin need more enmity generation options though? Of course. When Warrior has DPS, Antagonize, Sentinel AND Collusion there's an issue. However as was also stated before, enmity management is a group effort. Any group that does not understand this is doomed to fail. It is up to the non-tanks to keep their hate low and it is up to the tank to keep their hate high. If this does not happen then potential problems arise. Paladin could use a couple of extra enmity generation tools but if the party is playing well then Paladin is usually fine in this area.
