Yeah, but not to worry, I'm sure mods will fix it. Or at least make it slightly less silly. What I'm more worried is streamlining of warfare. Now granted, CK2 with it's over-complex systems that the player had little to no impact on was hardly great in this regard, but this seems like instead of fixing it, they just stripped everything to a bare minimum they could get away with. Two things come to mind:
1) The way levies (do not) work now. Now granted, the way it used to work in CK2, with needing to raise individual levies, combine them, then send them where you wanted them was an annoying exercise to repeat in every single war. But I'm not sure being able to just summon them in wherever part of your realm you want, no matter how far or how isolated is a good idea. It makes playing a huge sprawling realm even easier, and isolated enclaves far more defensible. But the worse part is that past early game, levies are absolutely worthless: Man at Arms not only upgrade dramatically, but they can literally teleport across your entire realm. You can teleport an army right in the path of a moving enemy stack, completely destroy them because of how powerful MaA are, then raise them the same day on the other part of the realm to repeat the same.
2) Instead of finally adding naval battles and blockades, they completely stripped away that part of the game by making armies walk across water. Besides how stupid it is for there to always be enough ships around for everyone to hire, even if they are in massive debt, even in the middle of nowhere, even in hostile territory, even if they are broken and running, even if they are a fucking peasant revolt, this change has a massive impact on warfare now. AI uses ships to a ludicrous degree, sailing great distances simply because it's slightly faster than walking, constantly landing at your capital, and after defeated running away to sea with no way for you to stop them, making it even more important to field MaAs, because only they can cause enough casualties to avoid having to repeat the same thing again and again. I cannot emphasis enough how much I hate what they have done with this.
Combined these two changes make the map feel small and distances inconsequential. A landlocked Bavaria should have trouble getting troops to help their ally in Ireland, that was a good thing for fuck sake. Now it feels like everyone is right next door and can send their armies everywhere at a drop of a hat. Seriously, fuck this shit.
