We do NOT have "Paladins" under the MMO definition in this game. We have Knights, or royal guards who protect guard the Sultana.
In most MMO's a "Paladin" in lore is a person who belongs to a church/religion, and who's very existence is to purge the darkness in the world.
XI - Paladin belongs to the church in San'd O.., and is given strength to fight un-dead.
WoW - Paladin belongs to the church again, and is fighting against the un-dead.
Both are blessed, have magic, use "holy" arts, healing ability, heavy armor/shields, playing a PLD in both games gave a very unique identity.

XIV - we have a knight who might as well have been a squire under a PLD, learned a skill or 2 and became a sell sword.
