I'm going to have to side with Thief on this one. I was debating between a few classes like soldier, black mage, and thief, but as soon as I saw why you relate to Balthier and Vanille, it pushed it more towards thief, because I always associate being quick-witted with thiefs (and he is a pirate afterall). Your enthusiasm, reminds me of many of the thiefs, along with how you described your sense of humor, and even that you mentioned being bossy (Yuffie much?). The overall tone of your application and many of the answers make me think you'd do best in a fast paced battle type with similar skill sets, and since thieves can work alone or with a team it's a great type for you.
