I would really like to see an option to customize the music we hear when we initiate battle with both regular mobs and bosses. I liked the system in Dissidia where you could choose your battle theme before the match. All the battle themes from across the Final Fantasy games could be added in. There could also be an option to have random themes played for both regular and boss encounters. With so many themes to choose from, this would add a nice kick to battles in FF14.
