Troublemakers are cancelled out by other troublemakers and diplomats. Should never be a problem. And make sure you contract your people with special R&D skills as soon as you get them. The auto-dismiss thing fired my Materials Engineer and I had to go get a new one.As to soldiers though, I am playing this so slow that I am already now by mission 17 nearly filled up with minimum B rank, most of which have special skills. Combat soldiers all have A rank. I like the feature where they auto dismiss lower ranks due to base being full. I thought the waiting room was infinite, but apparently not. So I've just started letting it auto sort members for the most part. I fire all troublemakers regardless of their stats.
The cap is 700 per base, by the way. As soon as I got my FOB I took a tour of Africa and did all the side missions, and fultoned out pretty much every soldier on the map regardless of level. A few missions later and I'm just filling up the waiting room again (building the FOB to rank 4 is really fucking expensive and takes an absurd amount of time, but at least it's real time and not in-game time) so I only take people who are at least A+.
