My first character will almost certainly be an Elezen. I chose a Hume in FFXI because of the statistical balance--I had no idea what I wanted to play at first, so it seemed a sound idea--but regretted the decision later for aesthetic reasons; I felt bland. I like tall elves, and both of the clans of Elezen have good roleplaying potential. (It is possible I will change my mind and make a Mi'qote, but I'm leaning way towards Elezen.) As for a discipline, Lancer looks promising.
I will start in Gridania because I love forests, especially those of the large, mysterious kind. My favorite place in Vana'diel was the Sanctuary of Zi'tah, and I hope to find equally beautiful places on Eorzea.
