Originally, I wanted to be an Archer that is just a ranged DPS, so you could imagine my annoyance when the related job was Bard (To the point where I refused to use the job crystal until I absolutely had to). Then when Rogue/Ninja came out, originally I just wanted to try it. But with it containing multiple things I liked (Duel wielding, a bit of magic with Mudras, some ranged skills), it's now my favorite Job. I may switch to other jobs from time to time, but I always go back to NIN at the end of the day.
