Ishgardian classes

There are a handful of other games where they can use a scythe, but as near as I recall it all started post XI anyways. So Greatsword makes the most sense if you want the most "classic" Dark Knight weapon. It also fits the armor look more.

And they have plenty of tanking qualities. There is more to them than just the Darkness ability, even if it's the most iconic.

Actually, no, there are not. There is just one Final Fantasy game that they use scythe in and that is XI. Side note, I will concede that in the upcoming Final Fantasy Explorers game, Dark Knights do use a Scythe in that game, but I do not know if they have access to multiple weapons or not. Just that I've seen a picture for that game with one using a scythe.

FFIV.


FFX-2.


Not many other games show their pictures of Dark Knight, except Bravely Default.. which is pretty much a non-Final Fantasy, Final Fantasy game.
