Since I've been banned from Paradox Forums several times, you all are my sounding board now.
Since this whole new combat system is based around generals, there really should be (but to my knowledge isn't) some "fog of war" on generals traits. Generally in real-life you don't know who's a Napoleon until they've proven themselves by their achievements. So, my thinking is you have an actual hidden General skill score/traits, and a projected General skill score and some hidden traits, with a correlation between the two and the skill levels/hidden traits revealing themselves/being revised more closely as more battles happen.
This would make it where you have (like a real ruler) moments where you're left guessing if six-star General Thundercock just had really bad luck at the Battle of the Doomstack or if he's actually a paste-eater and was only ever good at parading and passing West Point exams. Or, when your general gets assigned to some far-off colonial post because he's a Coward but turns out to have a knack for commanding troops in rough terrain and goes on to conquer the colony singlehanded.
This post was inspired by the many times a general had to work their way up instead of the All-Seeing Government knowing who to put where. (Grant replacing McClellan, Zhukov replacing whatever clowns were ahead of him, etc.)
Really want there to be inter-general interactions too (I think I've rambled about Tannenberg before), but I doubt they put any thought into that. Things like generals forming special bonds that make them work better together (Jackson and Lee) or bitter rivalries that make them go together terribly (Samsonov and Rennenkampf), or generals acclimating to fighting other specific enemy generals (famous rivalries like Patton and Rommel), etc. It could also be really cool if commanders could have specialties in specific enemies (Yamamoto having more insight into fighting Americans, for example), or even false traits where they get real lucky in a battle and they get some false trait/score that isn't real (Custer).
Fog of war like that would be really useful in character-driven games like Crusader Kings (can't tell how much they like you, just whether or not they act like they like you), but it was more important we get lolsatan and The Sims instead.
