I'd like to see more unclickable NPCs wandering, gathering, interacting with each other, etc. before disappearing.

I remember I once found a wandering NPC at a far edge of the map in Coerthas Western Highlands. I think he was wearing retainer outfit and had a Chocobo walking alongside him before shortly disappearing. It was pretty surreal as that was the only time I've seen it happen. They weren't clickable and I would've easily missed them as I was flying by in a hurry. I'd like more of that as it adds a bit more of life to the open world even if it is artificial.
