Nah, you always need SOME staff. If just to tell you what scripts are needed while you're asleep.

"Yeah, could you script the system to recognize when everyone on the server dresses up in this patern and starts using these racial epithets?"
"Also, you need to detect when a guild is lining up in a no-weapons area along the exit and have them not be able to block everyone on the server inside."
"Also, someone's got a new trainer that, while it can't hack the serverside scripts, it can make the server think the clientside script of these minigames is saying the player wins every time..."
You'll always need GPs. They're the final word in Runtime Staff.
LATs are primarily compiletime staff. They stand upstream and try to fix things systematically. They need just enough power to test how it's working.
FAQs and GCs should be players. Ashes to ashes, dust to dust.
