I’m not sure what the priority is (or should be) of the AI, the management of computer teams. But I think there is a relatively simple way to improve it: let them not ignore stamina and rotate players more. So to add a rule that a computer team won’t play with players under stamina x if there is a decent replacement.

That would also help managers from 2nd tier national squads – who have only few options of decent players, and they are usually burned out by the time the WC is played!

That is in our list already, I’ll try to implement it sooner rather than later. We had a couple other improvements related to AI but, as you said, they usually have lower priority when compared to features that will have direct impact on the human managers experience. One of them would be to have the AI mimic human manager formations and have more varied tactics, but I was afraid it could make them too strong in some cases.
