Yeah, it's a typical "nice from far, far from nice" idea. they managed to eliminate completely insane peace deals when you joined a war as an ally, did nothing for 30 turns, and got 90% of AI's cities. Unfortunately, with the point system, I cannot imagine a working solution. We'll be conquering cities simply by slaughtering brainless waves of enemy troops if we'll be able to manually change peace conditions with the current system.
