It's still a cop-out though - the very term 'Warrior of Light' was only really associated with the early NES-era games and had all but disappeared from use by FFVI (and even then FFII did not use it at all, neither did FFIV from what I remember - even FFXI, a game mentioned by it's former producer as being "everything we wanted to do with FFIII originally but couldn't due to the technical limitations of the time", did not feature the term - it used the term 'Crystal Warriors' instead, but even that was not used for the player's character and ended up referring to something completely different).

Only since FFXIV has the 'Warriors of Light' term come back into use, mostly due to SE returning to it's roots and featuring a lot of callbacks and references to it's history in their most recent FF titles, FFXIV included.

So yeah, once again I'm not going to take Gilgamesh's ramblings in a spin-off title as reflective of events in the main series, especially not FFXIV.
