Game-wise, I believe that the storyline is the same for people from 1.0 as well as new people for ARR. That being the case, I think the game is geared to make you think that you are a hero from Carteneau and before it. Otherwise, it's left open to interpretation.
For RPers I think no one really minds if someone new to ARR claims to have been involved at the battle so long as they've got their lore straight and in reverse, many people who carried over from 1.0 didn't go anywhere near the battle.
