I use forts, though less (so far) in MTW2 than in RTW, where I used them a lot as strategic defensive posts.

But I keep forgetting the use you mention here. It's annoying having reinforcements go rebel not just for the loss of troops, but because they then cost you more troops in removing them from your reinforcement path. And all it takes is an agent to keep the fort "alilve." Or a unit chopped down to a couple of men. The 500 cost is paid back pretty easily if you prevent one unit from going rebel. The ongoing support cost can be very low if you use severely depleted units or agents you would park in that area anyway (like spies keeping an eye on things). Or if you have a steady flow of units passing through so there's always one there anyway.

As far as the AI use of forts goes, they seem to not build them. But they sure did like using them in RTW. One downside of using them defensively is the AI would take and hold them, effectively stoppering your bottleneck in their own favor. But that still mitigated an invading army's threat level, so it was very much worth it. The AI tended to park the army that took the fort in it and just sit. Fine with me.
