Manually moving around units to exploit the AI does not help the verisimilitude of the simulation. Conversely, if you aren’t exploiting the AI, then it’s just busywork that can be automated…
Complete rubbish. History is full of examples of small forces outsmarting and outmaneuvering larger forces. The same applies here.
I don’t think you understand what Victoria is or at least was before V3 mess came out. It is NOT an economy simulator. It is a geopolitical simulator and war is inherent part of it - or was in Vic1&2.
And you don’t have to (and often you are unable to), but least you have an opportunity to do so. A choice.
Battalions? Not necessarily. Divisions (like in V1) or brigades (V2) very much so. If you want to make a ridiculous strawman argument at least try to stay accurate.
