My first Final Fantasy game ever was FFIV (named II back then) in 1992. Its main character was a Dark Knight turned Paladin. Plus, I've always liked playing tanks in whatever MMOs I've played and I like the "Holy Knight" meta that Paladin is.

So I mained PLD in XI. I mained Templar in Aion and GLA in XIV. Needless to say, I didn't complain when it was revealed that PLD would be GLA's Job Crystal.
