Except its not about hitting the space button, its about having a checklist of things to do when event XYZ happens. Aka war happens: 1. raise maintenances. 2. check for fleets. 3. ??? etc.
This is exactly why you have advisors and suchlike, so you dont drown in micromanagement.
Or would you like to pick the roads your troops march on for every move they make? Micromanagement should be optional.
Yes, when you are at war, you have things to do, sorry, don't see a big issue. I prepare my war or i prepare myself to a war. When it begins, i check my 4 or 5 fleets (you don't need more to patrol, even if you're a world empire, and if you're a world empire, you should not be frightened by a war), keep them safe, raise my maintenance etc. It's a Paradox game, you have some things to do, and check 5 fleets is not a big deal.
And what's your solution: AI do everything ? No patrol ?
I do'nt understand your logic: "everything should be safe, because i don't want to loose a single ships in a war." Sorry, i like to play in a game where, if i want a well managed empire, i need to protect the roads with ships, even if it's dangerous during a war.
Yes i love planning some stuff for my empire. I like creating patrol roads, area for patrol fleets, have a port with a big fleet to protect the patrol fleet if a war begin etc... If i take my 3 fleets exemple for america, i have always my biggest navy on an Caribean Isle, so it can protect the patrol fleet in the first month of the war. I managed my empire during peace, so i can be safe when wars begins.
