Requests: Nerfed Mercenary Cards, Ironman Mode & AI Generals

Explanation: The AI in this game is vastly outgunned by the players in almost every respect (atleast in the story mode). We can amass mercenary cards before ending our first campaign, save and reload every battle, and employ generals or ourselves in battle to tip the odds. The first problem, massed mercenary cards, can be fixed by simply removing all such cards at the end of each campaign. The second can be fixed with a sort of Iron Man Mode, such as in Crusader Kings II or Europa Universalis, wherein you can only save and quit.

But the final problem deserves special attention. We are facing rivals in the game that, besides the whole dragon thing, should be on equal terms with us in the war for the throne. Don't they have trusted soldiers that can lead battles in their place? Can they themselves not be bothered to fight for their rights?

My proposed solution, simply put, is to input the chance that the AI will employ it's own generals. We don't need cutscenes or even a story - just a picture and stats to augment an army. As a bonus, make the AI army during these fights act differently for each of these generals. This would make battles more personal, rather than tiresome affairs to be auto-resolved.

What do you guys think, are these good ideas? Have they been proposed before?
