Reason: players, even (or especially) casual players like it when AI act sensibly and keep their alliance with them. I know it's Total War but the game's diplomacy that actually works would please many people indeed, hardcore fans or not. People tend to keep their alliances with a trustworthy AI for a long time or even for the rest of the game if the CA coders fear for their lives and want them to have a chance

2. Protectorates honours their "alliance" with you first even if you are the aggressor against their allies. A simple code change, I believe.

Reason: It angers many people when they lost their protectorates just because they attack that protectorate's allies. It's absurd and often forces you into some irritating diplomatic position ("I forced [faction] to be my protectorate but why the **** is this subject of mine betray me for their ally? I'm their master!" - situation happens often)

Maybe a trigger that make your rival ally (which is stronger/bigger/bordering) to attack you when your faction leader dies only.

Just a thought.
