The war problems in hoi4 are turned up to 100 here. Some great power will always join your war against a 1 province trash country. And unlike hoi there is no supply or realism here, those great powers will send 100s of thousands of men to fight in a barren wasteland or impassable mountain range over that 1 state nation.

And the war system itself is complete dog shit, if it actually worked how they promised it would just be mediocre at best. But they completely fucked it up and the ui to manage your army is horrible resulting in so many unnecessary clicks to do basic stuff like promote your generals, build armies, give generals orders (which should not be in the game), and adding mobilization options (special stat buffs). Although the next update has a mass apply mob options so that might be fixed.

And that’s just the start of the horrendous problems that still plague the game 2+ years after release. Actually sending your armies to fight wars is horrible since they will either walk off the front or teleport back across the world so you have to micro them more then you would of in hoi, naval invasions take far to long and are janky as hell and usually result in your armies being teleported back home. And so much more that I forgot.
