I probably complained about this, but my god, Vic 2 battles.
128,000 Russians versus 20,000 Prussians? The russians will take 3,000 casualties for every 800 prussian ones no matter the situation. 20,000 Russians for 128,000 Prussians? There will be, max, 2000 enemy casualties (playing as Russia.) Despite having 0 brigades, enemy nations will rarely surrender even for light victory conditions. There is apparently no such thing as tactics in a battle and fighting is a pure meatgrind. A fight of about 35,000 combatants will take a month to finish.
Did the devs actually do any historical research in the slightest?
