They're really all but forgotten, but yes. I would have liked more interaction between class/job NPCs.

To see the ACN guildmaster interact with Alka Zolka/ Surito Carito

Actually, would love to see more of them, period.

One of my fave parts in game was:
When the 3 WHMs summoned Y'shtola from the Lifestream and with Y'mithra there.
