The AG's only meaningful task lately is to put bills onto the Wiki. That job can be easily transferred to the SoFA, PPT, or Dean of the Senate (who could act as a type of Senate Clerk). It has no real purpose, as they've represented Atlasia in court about twice in our history.
State, Defense, and Treasury honestly don't do anything critical to the game right now, and until population is up and we have an active GM, I'm fine with not having anyone active in that position, as it doesn't matter much.
It was more than twice - way more, at times - but otherwise I concur with the Senator's sentiments.
