Other than turn times increasing and sometimes being harassed by too many agents (shadowing) the main vanilla issue is: the AI often leaves legendary heroes on the map instead of putting them into armies, so you never have to face these strong units in battles. Having them embedded via mod gives players a chance to fight them in combat and the AI's army improves.

It would maybe be nice to have a mod that only tries to embed legendary/immortal heroes. ;-)

There are many who do not share your opinion and experience the opposite. I'll add that clicking the subscribe button is entirely optional.

This sounds like a terrible idea when armies full of too many single entity agents is already a problem tbh

Perfect. I hope this works. The agent shadowing was annoying. At least with your campaign AI mod the agent action frequency was significantly higher. My top lore of fire Daemonsmith kept getting wounded almost as soon as he spawned. Probably infuriating for most people but that's how it should be. In vanilla, they just follow armies around and don't do anything.

"AI will attempt to leave less heroes/agents on the campaign map". How does this work in your implementation ? We use another mod that embed egents when AI can but we are still swarmed by AI agents.
