Try setting things on fire. The AI's will just lose their mind. They're also trigger happy. As soon as they get on a gun and someone is almost in arc, they'll start firing. I've seen AI try to empty entire clips into an enemy that was above their firing arc. Other times they'll jump on the gun and start shooting immediately, while turning the gun to the target, wasting half the clip. They also seem to enjoy loading heavy clip into the gatling. I'm not sure what ammo they load into other guns, but heavy clip stopped being useful in the gatling gun many many moons ago.
But yeah, they could definitely get some priority adjustments when picking what tools to use when. Nothing makes my engineers angrier than an AI showing up and messing up their cooldowns. Of course the AI will never be as good as a human player, since they're entirely reactive, where human players can predict damage to certain components and plan accordingly.
