I liked seeing the different starts to the main story based on where you started. On my main I started in Limsa and on my alt I started in Gridinia. Also, one is a Miqo'te and one is a Hellsguard Roe, so they look very different. It was fun playing with the character creator. The biggest advantage to me personally was being an arcanist on both and taking one down the summoner route with full 30 in intelligence, and taking the other down the scholar route with 30 in mind.
