Give it time. We are in the second year of ARR, I am sure in time you will see many glamour outfits from other Final Fantasy titles during this game's lifetime. While XIV is it's own game, it is also a fan service title as well. There are numerous characters that all were important in their respective titles. I was actually surprised they even had included Cloud's AC outfit into the game, but this merely opens the doors for future character outfits. Currently available are Snow, Lightning, Cloud and Setzer. Techincally the Warrior of Light from FF1 as well if you consider the tank set from LotA paired with the Helm of Light.

I can see us getting other outfits in the future. We don't need to have them all "Now! Now! Now!"
