It stands to reason that the player character, being a cut above the average adventurer, blessed with the power of the echo and so on would single-handedly end Gilgamesh's pseudo-undefeated streak. The set up is definitely there.
To be fair, that's pretty much the exact same as he was in FF12. And honestly, I can't think of an exciting 1-on-1 fight in this game, or one of any length or depth. The only way to do justice to Gilgamesh demands a fight that requires a party. Especially when you account for Enkido, who they hopefully remembered to include.
