That makes no sense. Kain used spears, all named Spear or Lance, and Kain was the third dragoon to make an appearance -- FF2's Ricard Highwind and FF3's Dragoon both wielded spears as well. Moreover, while we call the class Lancer in FFXIV for whatever reason, lances are a mounted weapon and lancers are cavalry. Chalk it up to translators taking excess liberties with naming, as the Japanese name apparently amounts to spear specialist.
Except it didn't have any additional effect as a Paladin. Cecil never had any abilities at all related to the shield, and there has never been a shield in his animations whether Dark Knight or Paladin. The shield was always a stat stick in FF4, and shields didn't even display in any capacity.
There is a lot from the trailers not realized ingame, you know. That aside, having a two-handed sword job does not mean Dark Knight, especially when Dark Knight does not traditionally use said weapons. If you're going by appearances, then Red Mage from FF12 International could wield greatswords, and Knight/Paladin has the most appearances with the weapon (11-12i-TA-TA2).
