What could DRK have learned from FFXI?

If you're making a claim based off of HP scaling, then you should also make a claim based off dps scaling. If Cecil as a Dark Knight is definitively a "dps", then he should be doing more damage as a Dark Knight than he is as a Paladin. That clearly isn't the case. He has less stats across the board. The reason why his stat scaling is weaker as a Dark Knight is because you're expected to climb Mount Ordeals at the level 15-20 range as a Dark Knight and come down as a level 1 Paladin. You can think of Paladin as being his "job upgrade", similar to the Fighter -> Knight transition in FFI. So I don't think that argument really holds up.

The issue is that DRK Cecil is not tankier that other frontliners you have in those level range, whereas PLD Cecil, outside of using the overpowered Ragnarok, clearly do less DPS than other frontliners at endgame.
