Off the top I want to say I'm absolutely loving the Namazu questline - the adorable lil guys give a lighthearted touch not unlike the Moogles did, and with perhaps a more fun story behind them!
Thing is, and it might well be just me, but I can't help but notice I've been stuck with the same three early stage quests, only getting anything different when my reputation ranks up.
Not a really big deal, but something that could make it get old fast if it's a whole lot of the same (although granted, it hasn't even really been a week yet, so we'll see)
