I know the mechanic is a CK3 thing, but armies enemy of my enemy being hostile sucks ass. It makes zero sense that the Reunited Kingdom's armies are hostile to my "second alliance". The AI is also stupid and will target my troops, so I have Aragorn ♥♥♥♥♥♥♥ down the elves coming back to help lol. I'm not sure how I would get strong enough to fight Sauron without a proper gang up.
