It's not really a serious question. I know that SE couldn't resist the big FFIV DRK -> PLD transition reference. Just feel free to voice your own thoughts on the why of it.

For me it's like, "Oh hey, in Seat of Sacrifice, Elidibus was really onto something... I'd look cool with a sword and shield!"

I mean, it does seem like the WoL is easily impressed by other jobs when they're shown.

Like from ARR -> HW the Derplander is walkin' in, and sees a DRG or two just straight up delete a dragon, and then immediately trades in the WAR stirrups for that sick gauntlet, kah-schungt!

Then in Stormblood they're Monk to properly spar with Lyse I guess, but go on to become Samurai after the Far Eastern excursion, I guess mainly to fight on parity and beat Zenos with the own weapons that he wields.

Shadowbringers he seems to have switch to DRK out of necessity to fight with the Lightwarden/Sin Eater in the trailer.

But so far, for Endwalker it doesn't really seem like there's a reason outside of the script calling for it. A gil for your thoughts?
