One thing that I always had a problem with is that most of us assume that we have to/do follow Hydealyn's command. I mean, our characters get blessed by her, but at that point we can just say "Fuck it, I'll become an insanely perfect crafter like no one ever was" and never bother following her words again (although that does lock us out of Ishgard and lots of other content, but that's just the natural course of things because that way we never meet and befriend the people necessary for it).

I have a lot of trouble placing the WoL in Lawful, because we don't give a damn about the rules or orders we get in general. Some random dude comes up to us and is like "I give you Gil and Exp if you steal stuff from my business rival / make him have an "accident" / poison those people / etc." and we go ahead and do it, because it gives us what we want at the time, or we don't, if we don't feel like doing it. We ignore authority all the time, and even when we couldn't hear Hydealyn, who is considered the ultimate greater will, we kept on doing whatever we wanted to do, even if it may had been completely contrary to what she wants from us. Chaotic wouldn't be fitting either because the one thing that's really obvious is how much our character cares about his bonds, always ready to do whatever they ask of him (if we go by a "you must do the story"-approach and ignore that you can choose to not do anything with your blessing). We don't value freedom THAT much.
So, all in all, I'd probably go with..Neutral Good? (Or True Neutral, if we consider that our characters are totally ready to do some pretty evil stuff if it gives them those sweet sweet Gil to buy that new dress they want..).

Oh but whatever, this has been talked about in bigger threads by many people already. I don't wanna go full-on alignment talk again and just stick to a discussion about what Thordan's last words mean xD
