Yes I can't because several aspects of it are outright unfun or broken and few mods address it.
The azure patch absolutely broke the balance of the game through broken faction mechanics and very few mods address this. But regardless of that the games warfare system is significantly less fun than CK2 because of fundamental issues and absolutely no mods can really address them. Cheap things like auto wins and loses based on sieging capitals, absurd amounts of chasing armies because how many tiles are available, weird inheritances and outcomes from the men at arms system, armies capable of crossing the map through neutral territory and running away through ships, no control over you allies armies and very very questionable AI decision making actively working against the player.
There's countless threads on these fundamental issues and as cool as the Royal Court DLC looks it addresses none of the major issues with the game and is actively bottlenecking fixes the game desperately needs.
I love so many aspects of CK3 over CK2 but when it comes to war and having actual AI succeed at anything I have to play CK2 and those are so fundamental to having fun in the game. It just sucks to wait.
Okay, let's see...
Broken faction mechanics? I've yet to experience that. If anything, factions in my games are more reasonable than before Azure. My word against yours, then?
Auto wins and loses based on sieging capitals are not a problem. You're supposed to be defending your capital. If anything, the AI should be told to prioritize defending their capital more.
Absurd amounts of chasing armies is just a result of the AI being smarter and running away when at a disadvantage (usually). Not a problem.
Weird inheritances and outcomes for men-at-arms is more of a bug than anything and, honestly, it doesn't happen as often as you make it out to be.
Armies capable of crossing the map through neutral territory is not a problem. That's exactly how it was in CK2 and I want it to stay that way.
Armies being able to spawn ships is by design and I personally have no problems with it.
No control over your allies' armies is the only thing I can really agree with. And it's even worse when you're not the war leader because then the allied AI armies will just ignore your existence and won't help you even if you'd be able to win a battle with their assistance.
In short: You're dramatizing. Saying that you "can't even open the game without having a bad taste" in your mouth doesn't make you sound serious.
