I can't even get a general that isn't terrible. I spammed 400 military power hiring generals and they all had 1 or 2 points in a couple of categories.
If it's the same as EU3 you should save up as much power as you can before making generals, increases their base stats. In EU3 I'd always wait until 90%+ tradition before making generals, and they'd always be 4-4-4+s, not sure how EU4 works though.
Oh, and about the tactical side of things: Terrain is most important in Paradox titles. River+Mountain = attacker loses, bottom line. I wish EU had a more HOI-like system with flanking and pincer attacks. Otherwise; for wars like yours your only bet is to create doomstacks at a size just below attrition and mass wave them until you win.
Dunno if I'll pick this up. Seems to be a pretty normal Paradox launch, but with more rush. Will gladly wait until patches and mods to shore up the glaring mistakes in design main one I saw around was making state religion go to Christian
with no goddamn option at all on westernization, due to the 'White makes might'* theory of Paradox titles. Coalitions, too, that bit scares me.
EU3 wasn't necessarily stellar in espionage areas, either, so I don't think I'll be very motivated to bother fucking with currently-broken coalitions at all. Feel like it'd just be a rush to grab all the minors you can before unbreakable coalitions form everywhere.
