I love heavy physical offense (albeit I typically prefer high offense + speed in my classes while sacrificing defenses), which the class can easily offer that with Death Wish + Insanity.
Plus, I have a tendency to like those black/dark knights in a lot of stories. Anazel for obvious reasons *wink wink* was a jobmaster that I liked a lot. Design-wise, the class reminded me a lot of Oswald from Odin Sphere, which was also fangirl fuel to me.
Summoner class is another I liked just 'cause I love all the beasties you can summon out in a lot of games (I would've loved a summon like Bahamut in this game as I love dragons, but Deus Ex was pretty cool-looking), but sadly I remember it being kinda useless offensively by the end of the game. Amazing MP pool though, if perhaps too much MP. I remember finishing with like 800+ MP by the end of the game.
