This might be considered 'taboo' in some places, but might be an interesting (and realistic) option:

Main male characters who are in love with each other? Perhaps Cid really left over a dispute with his true love, who is now raising an army to reclaim him?



Also, are there any inter-species couples in Eorzea? A happy Galka and Mithra living in a small village somewhere on the outskirts of Ul'Dah?



We could also have perhaps more anti-hero people in the storylines? Someone who makes us question moral and ethical dillemmas?
