The thing about Eorzean accents is they're not supposed to sound -exactly- like some real-world equivalent. It was brought up in one of the lore panels that the vocal team does have some sort of vocal requirement to sound a particular way though. That said, the English dub is trying to do something that sounds "older" and only so much vocal training can really modify a person's speech.
So they might kinda sound Scottish or Northern or something else or none of the above. I wouldn't be too concerned with it. Especially since only the english language in the game gets all those localization goodies. The other languages don't get all the archaic stuff or cryptic messages. Or all the cool lore-filled flavor-text until after the English team's written it. (Yes, the main script is usually in Japanese first, but the other localization teams generate unique content too!)
